Randomized Study of Running Shoe Cushioning Effects on Injury Risk in Adults 18 to 65

What this Trial Is About

Researchers are investigating how different cushioning materials in running shoes affect musculoskeletal complaints and injury risk in leisure-time runners. The study aims to understand if using extra soft cushioning materials at the rear and forepart of running shoes can reduce injury risk, how cushioning position influences injury risk, the impact of a runners body mass on these effects, and how runners perceive cushioning. The study also explores whether other weight-bearing activities besides running contribute to injury risk. Participants will be randomly assigned to one of three running shoe models that differ only in foam cushioning properties at the rear and forepart, varying by 33% and 37%, respectively. They will receive their assigned shoes and use them exclusively for running over a six-month intervention period while maintaining their usual training routines. The three shoe versions are tested for stiffness and cushioning, labeled as Hard, Mixed, and Soft models with specific cushioning levels. Randomization is stratified by sex to balance body mass differences. During the study, participants will complete a baseline questionnaire and weekly questionnaires on musculoskeletal complaints and shoe usage. Running data will be collected via sports watch apps or uploaded GPS files. The main outcome is the first running-related injury causing at least seven days of running restriction. Secondary outcomes include shorter time loss injuries and musculoskeletal complaints. Researchers will monitor adherence, send reminders for data entry, and follow up on missing reports. The total participation lasts six months from shoe receipt.
