Objectives There is a gap in research exploring perceptions of runners and healthcare professionals (HCPs) about running footwear and injury risk. The objectives of this study were: (1) to document factors considered by runners when selecting footwear; (2) to compare perceptions on footwear and injury risk in runners and HCPs; and (3) to evaluate the perceived usefulness of an online educational module.

Methods Using an online survey, we collected information on demographics and perceptions about footwear and injury risk. Runners reported their footwear selection strategy, and HCPs their typical recommendations. An evidence-based educational module was presented, and participants rated its usefulness.

Results The survey was completed by 2442 participants, of which 1035 completed the optional postmodule questions. Runners reported relying mostly on comfort and advice from retailers when selecting shoes. Perceptions regarding the effects of specific footwear types (minimalist, maximalist), characteristics (softness, drop) and selection strategy (foot type, transition) on biomechanics and injury risk were different between HCPs and runners. Overall, runners perceived footwear as more important to prevent injury than did HCPs (7.6/10, 99% CI 7.4 to 7.7 vs 6.2/10, 99% CI 6.0 to 6.5; p<0.001). Both runners (8.1/10, 99% CI 7.9 to 8.3) and HCPs (8.7/10, 99% CI 8.6 to 8.9) found the educational module useful. A majority of respondents indicated the module changed their perceptions.

Conclusion Footwear is perceived as important in reducing running injury risk. This online module was deemed useful in educating about footwear evidence. Future studies should evaluate if changes in perceptions can translate to behaviour change and, ultimately, reduced injury risk.

What are the new findings?

  • Overall, both runners and healthcare providers (HCPs) perceive running footwear to be important in reducing running injury risk.

  • Perceptions regarding the effects of specific footwear types, characteristics and selection strategy on biomechanics and injury risk were different between HCPs and runners.

  • Runners and HCPs found the online educational module designed in this study useful.

  • It remains unknown if such a module could lead to behaviour change and, ultimately, reduced injury risk.


Running injuries can significantly impact the ability of runners to maintain a healthy lifestyle that includes regular physical activity,1 which can potentially have a negative impact on physical and psychological health. Footwear manufacturers have designed many technologies in an effort to address biomechanical factors associated with injuries, such as the vertical loading rate (VLR) of the ground reaction force, and lower limb joint forces.2–6 However, scientific evidence showing any consistent benefits of these technological features on injury risk is lacking.7 8 According to randomised controlled trials, cushioning features such as heel to toe drop and midsole hardness,9 10 as well as recommending footwear based on foot type,11–13 have failed to reduce injuries.

While research has yet to show the superiority of maximalist or minimalist shoes in preventing injuries, it is apparent that various types of footwear cause runners to run differently and shift loads to different body parts.14 Greater running shoe cushioning tends to increase VLR15–17 and knee joint forces,18 but decrease ankle forces and peak foot pressure. Conversely, lower cushioning tends to shift initial foot contact closer to the midfoot or forefoot, thus decreasing VLR19 and knee joint forces,20–22 but increasing ankle forces and foot pressure.22

Runners and healthcare professionals (HCPs) may or may not be aware of the current state of research on running shoes. There is a clear gap in research exploring the perceptions about running footwear and injuries among runners and HCPs, which has the potential to influence behaviour and running shoe selection.23 Educating these groups on current evidence pertaining to footwear is important, and may potentially aid in reducing injury risk. The primary objectives of this study were: (1) to document factors considered by runners when selecting running footwear; and (2) to report and compare the perceptions of runners and HCPs on the influence of running footwear on running biomechanics and injury risk. Second, we aimed to (3) evaluate the uptake and perceived usefulness of an online evidence-based educational module in both runners and HCPs, and to conduct exploratory analyses on its effects on perceptions.



A web-based survey was conducted between 10 April and 30 June 2019. Participants were recruited through social media (Twitter, Facebook, Instagram, LinkedIn), running groups and sports equipment stores. To be included, all participants had to be aged 18 years and older, have access to the internet to fill out the survey and speak English or French. Runners also had to declare that they ran either recreationally or competitively at least once per week for a minimum of 1 month, while HCPs had to declare a license to practice a medical profession (eg, medical doctor, physiotherapist, chiropractor, athletic therapist, podiatrist, pedorthist, osteopath).

Study design

After providing electronic informed consent and self-identifying as either runner or HCP, participants were directed to the corresponding set of questions on demographics and perceptions about the importance of shoes in reducing injury risk. Thereafter, participants were offered the opportunity to read an optional educational module summarising the current state of evidence about running footwear and injuries. After reading the module, participants were asked to rate its usefulness and responded to the same set of questions, to enable exploratory analyses on the effects of the module on perceptions. The design and administration of the survey consisted of five steps. The final version of the survey and educational module was designed with the help of runners, running shoe retailers and HCPs from the community. Patients and/or the public were involved in the design, or conduct, or reporting or dissemination plans of this research.

Step 1. Designing the first version of the online survey and educational module

We reviewed the scientific literature on running footwear and running injuries and synthesised findings into main constructs. First, we retrieved articles on the association between running biomechanics and running injuries, which outlined VLR2 3 6 and joint loads4 5 as relevant risk factors. Second, we identified the definition of minimalist shoes24 and the literature pertaining to the effects of minimalist19–22 and maximalist15–18 footwear on VLR and joint loading. Third, we identified clinical trials on the effects of cushioning density9 and heel to toe drop10 on running injuries. Fourth, we retrieved information on how transitioning between different footwear categories can increase injury risk.25 Fifth, we identified studies related to the prescription of footwear according to foot type and injury risk.11–13 When available, we prioritised systematic reviews and randomised clinical trials as references for the educational module. A total of 12 educational infographics were built and grouped into five sections.

The general set of PRE questions pertained to demographics and perceptions about the importance of shoes in reducing running injury risk, as well as their effects on lower limb biomechanics. We ensured that questions were related to the information presented in the module. Runners also provided information about their running habits, criteria for selecting running shoes and sources of information on footwear. The HCPs subgroup answered questions about the importance of footwear in the treatment of running injuries, and clinical recommendations pertaining to runners with knee or foot pain. The first version of PRE included seven questions that were common to both subgroups. Ten and five additional questions were designed for runners and HCPs, respectively. Some questions included subquestions.

Finally, we designed questions for POST, including the overall perceived usefulness of the module. Some questions were duplicates from PRE, enabling us to explore if the module changed the participants’ perceptions. Finally, a series of questions were included to ascertain whether the module changed how participants would select their next pair of shoes (runners) or provide clinical recommendations in the future (HCPs). A total of six and seven questions were designed for runners and HCPs, respectively, of which four were identical between groups.

Step 2. Feedback on the online survey and education module

The first version of the survey and educational module was sent out for review to individuals external to the research team. Six individuals (two runners, two footwear retailers, two HCPs) provided feedback on the relevance, clarity and interpretation of questions, as well as on the clarity, design and relevance of the educational module.

Step 3. Finalising survey items and educational module

Following feedback, we modified wording for 8 survey questions as well as wording and design of all 12 infographics. We also added multiple choice options for survey questions. The full version of the survey and educational module can be found in online supplementary files 1-2.

Step 4. Translating the survey and educational module

One member of the research team (JFE) translated the final version of the survey questions and module into French. The French version was sent out for review to three runners, one footwear retailer and one HCP who had French as their first language. Minor modifications to wording were made before reaching the final version.

Step 5. Administrating the survey and education module

Online versions of the English and French questionnaires and module were housed on the XM Qualtrics survey system ( After selecting their language and reading an overview of the study objectives and inclusion criteria, participants provided consent and self-identified as a runner or HCP. Following completion of the survey, the optional educational module was provided to those who expressed interest. Finally, participants were offered the opportunity to respond to the POST questions. Perceptions about the importance of footwear in preventing and treating injuries, as well as the usefulness of the module were rated on scales ranging from 0 to 10 (0 = ‘Not important/useful’, 10 = ‘Very important/useful’). Agreement with statements about potential effects of footwear on biomechanics and injuries and clinical recommendations was assessed using scales ranging from −10 to 10 (−10 = ‘Strongly disagree’, 0 = ‘Neutral/Uncertain’, 10 = ‘Strongly agree’).

Data analysis

English and French survey data were merged into a Microsoft Excel (V.2016) spreadsheet and analysed by subgroups of runners (RUN) and HCPs. Perceptions of RUN and HCPs at PRE (continuous variables) were compared using independent t-tests (normal distributions) or Mann-Whitney U tests (non-normal distributions). Perceptions between participants who responded to PRE only were compared with those of participants who responded to PRE and POST using similar methods. Finally, exploratory analyses were conducted to evaluate the effects of the module on perceptions. Specifically, PRE and POST scores for both RUN and HCPs were compared using paired t-tests (normal distributions) or Wilcoxon signed-rank tests (non-normal distributions). For HCPs, recommendations to runners with knee or foot pain (categorical variables) were dichotomised and proportions were compared between PRE and POST using McNemar’s test (2×2 tables). The α level was set at 0.01, and all point estimates were supplemented with 99% CIs. Statistical analyses were conducted using the Statistical Package for Social Sciences (SPSS, Armonk, New York, USA), V.22.



A total of 2442 participants completed the PRE survey out of 4520 individuals who visited the study website (RUN: n=1564; HCPs: n=878; 54.0% of all visitors). The optional POST questions were completed by 1035 participants (RUN: n=621; HCPs: n=414; retention=42.4% of PRE respondents). Of note, 87.1% of HCPs self-identified as regular runners. Demographic information for both subgroups is provided in table 1. Running-specific characteristics for runners are presented in table 2.

Selection of footwear and sources of advice

RUN most commonly valued comfort, performance and injury prevention when selecting footwear (figure 1A). Comfort (n=699) was the most frequent primary criterion, followed by injury prevention (n=197) and performance (n=177). Footwear retailers (n=409), specialised websites (n=287) and HCPs (n=209) were the most common primary sources of advice on running shoes (figure 1B).

Perceptions about footwear and injuries

RUN considered footwear more important in reducing injury risk than did HCPs (7.6, 99% CI 7.4 to 7.7 vs 6.2, 99% CI 6.0 to 6.5; p<0.001, table 3). RUN were relatively neutral with regards to minimal (0.2, 99% CI −0.2 to 0.6) or maximal (−0.2, 99% CI −0.6 to 0.3) cushioning helping to decrease ground impact and knee joint forces. In contrast, HCPs moderately disagreed with the statement that maximal cushioning helped decrease impact and knee joint load (−4.6, 99% CI −5.2 to 4.1), and tended to agree that minimal cushioning helped decrease impact and knee joint load (2.5, 99% CI 1.9 to 3.0). Both subgroups generally disagreed that softer shoe soles and greater heel to toe drop decreased injury risk, although HCPs showed a greater level of disagreement (p<0.001, table 3). Both RUN (5.1, 99% CI 4.8 to 5.4) and HCPs (5.9, 99% CI 5.5 to 6.3) agreed that transitioning to different footwear could increase injury risk. Finally, RUN tended to agree that selecting shoes according to foot type would decrease injury risk (1.6, 99% CI 1.2 to 2.1), while HCPs moderately disagreed (−4.1, 99% CI −4.7 to 3.6, p<0.001, table 3).

Table 3

Differences in PRE perceptions about the effects of running footwear on injuries and biomechanics between RUN and HCPs

Overall, HCPs perceived footwear as moderately important for treating running injuries (5.9, 99% CI 5.7 to 6.1). They generally agreed that injured and uninjured runners required different footwear recommendations (3.5, 99% CI 3.0 to 4.0). The majority of HCPs reported usually recommending less cushioning to runners with knee pain (61.6%) and more cushioning to runners with foot pain (53.9%).

Perceptions between individuals who responded only to PRE and those who responded to both PRE and POST were significantly different for all questions, except for the risk of injury related to transitioning to a different category of footwear (table 4). However, their age (p=0.879), gender (p=0.783), level of education (p=0.012) or running experience (p=0.06) was not found to be significantly different at the α=0.01 level.

Educational module: uptake, usefulness and changes in perceptions

The module was deemed useful to learn about current evidence on running shoes, with HCPs rating it slightly higher than RUN (8.7, 99% CI 8.6 to 8.9 vs 8.1, 99% CI 7.9 to 8.3; p<0.001). A majority (62.3%) of RUN declared having changed their perceptions after reading the module, while 50.1% mentioned that it would change how they select their next pair of shoes. In the HCPs subgroup, 54.8% said the module changed their perceptions, and 58.7% mentioned that it would change their future footwear recommendations. In regards to treating runners with knee pain, significantly more HCPs reported that they would recommend less cushioning after reading the module (+19.2%, p<0.001). Conversely, a greater number of HCPs said that they would recommend more cushioning to runners with foot pain after reading the module (+12.3%, p<0.001, online supplementary file 3).

Exploratory comparisons of perceived importance of footwear on injury risk between PRE and POST showed a statistically significant decrease after reading the module, both in RUN (−1.2, 99% CI −1.5 to 1.0; p<0.001) and HCPs (−0.5, 99% CI −0.8 to 0.2; p<0.001). More exploratory analyses of changes in perceptions after the module are presented in online supplementary file 4.

Running injury rates are high,26 and assessing knowledge about the effects of footwear on injury risk is potentially useful in addressing the issue. In a recent paper by Fokkema et al, nearly half of runners identified ‘not knowing what to do’ as a significant barrier to injury-prevention behaviours.27 This outlines the need for accessible and evidence-based educational resources like the online module designed in this study. Our primary findings were that perceptions about running shoes and injury risk differ between runners and HCPs, and that an online module is deemed useful to communicate the latest scientific evidence. This information can now be used to improve knowledge translation strategies to runners, and evaluate if improved knowledge changes behaviour, and ultimately reduces injury risk.

Footwear was generally perceived as an important part of running injury prevention by both runners and HCPs. This is in accordance with another study, in which runners ranked footwear as the second most important factor in preventing injury, just behind ‘progression of the training programme’.27 Our data show that comfort was heavily accounted for when selecting a new pair of shoes. Since runners in our sample ranked ‘injury prevention’ as the third criterion for selecting running shoes, it is possible that they also associate comfort with injury prevention.

Runners commonly search for information on injury prevention.27 Our sample reported seeking advice from footwear retailers and websites more commonly than from HCPs. This outlines the importance of designing trustworthy sources of information for the public, but also to educate HCPs to ensure they are seen as knowledgeable on the topic. This is important as HCPs play a key role in the clinical management of injuries, and runners must therefore feel comfortable discussing multiple strategies—including footwear—during treatment planning.

Despite individual variations, our data do not support results from a previous study which reported that runners commonly perceive wearing the wrong shoe for foot type as a risk factor for running injuries.28 Differences between studies could be due to our recruitment occurring mainly through social media. It is possible that our sample was more aware of the scientific evidence than the general population of runners. Similarly, the level of knowledge in our sample of HCPs (87% runners) may not be representative of all HCPs. Beliefs can be influenced by personal experience and interests. For example, our group previously found that recommendations about running and knee joint health were more restrictive when coming from non-running HCP than from running HCP.29

Our evidence-based educational module was deemed helpful by a majority of respondents. However, the fact that perceptions at PRE differed between participants who went on to read the module and answer the POST questions compared with those who did not outlines the need to identify and target individuals who may benefit from an educational module. It is possible that those who declined to read the module and answer to POST did not feel the need to learn, did not want to challenge their beliefs or simply did not have time. Importantly, it remains uncertain if changes in knowledge would translate into changes in behaviour30 and eventually, reduced injury risk. A recent randomised clinical trial did not report changes in injuries in runners receiving an online multifactorial prevention programme compared with a group who did not.31 Unfortunately, no follow-up on compliance to the educational programme or perception on usefulness was provided in that study, which limits the interpretation of their results and comparisons with the current study. Despite obtaining a relatively high rating for overall usefulness, the efficacy of our module in reducing injuries remains purely hypothetical and should be tested in a future trial.

The design and inclusion of the educational module represent a strength of the current study. Our rigorous process that involved feedback from HCPs, as well as runners without research knowledge, was essential in optimising internal and external validity.32 However, this study also has limitations. First, given that research on running footwear is constantly evolving, the module will need periodic updating when tested in future trials. Second, using online data collection may be subject to response bias. It is impossible to ascertain if respondents provided honest answers, including if they were indeed runners or HCPs. This is an intrinsic limitation of such a study design. Third, our sample may not be representative of the whole population of runners and HCPs. Many factors including sources and strategies for recruitment, language and level of education can have a significant influence on responses and the effects of an educational module. In addition, footwear perceptions and preferences have even been suggested to be country specific.33 Despite improving generalisability by providing the questionnaire in two languages, research is needed to help assess beliefs in multiple countries and languages to eventually adapt educational resources to different cultures. Fourth, differences in the perceptions of those who filled out PRE compared with those who completed both PRE and POST, and the fact that less than half of participants decided to fill out the POST questions, represent potential sources of bias and outline the need to correctly identify individuals who could benefit from an educational module. Fifth, the absence of a control group receiving no education precludes us from concluding that changes noted by exploratory analyses were indeed due to the module, since simply participating in an online survey study about footwear could have influenced responses. Finally, it is uncertain if the effects of the educational module would last through time, given that we only explored immediate changes in perceptions. Since respondents’ anonymity was prioritised, we were unable to follow-up at a later time.


Results from this study suggest that runners commonly seek advice from footwear retailers, and rely mainly on comfort when selecting new footwear. Overall, runners generally perceived running shoes as more important in preventing injuries than did HCPs. Perceptions regarding the effects of specific footwear types, characteristics and selection strategy on biomechanics and injury risk were also different between HCPs and runners. An online evidence-based educational module was deemed useful by both subgroups. Further studies are needed to evaluate if such an educational module would affect behaviour and injury risk.


We would like to thank all runners, footwear retailers and healthcare professionals who gave their feedback on the survey and educational module and all those who participated in this study.
