The aim of this prospective, randomized, single-group interventional study is to use quantitative methods to investigate the acute effects of using lateral-wedge insoles on lower extremity biomechanics, muscle activation patterns, and knee adduction moment during walking and running activities in healthy individuals aged 18-40. The primary research questions it seeks to answer are as follows:
* Do lateral wedge insoles cause a significant change in knee adduction moment? * Do lateral wedge insoles change lower extremity biomechanics during walking and running? * Do lateral wedge insoles change the activation patterns of lower extremity muscles during walking and running? To compare the effectiveness of lateral wedge insoles, participants will randomly use insoles with 0 (neutral), 5, and 10-degree angles.
Participants will do the following:
* Put on the shoes and insoles provided to you in the motion analysis laboratory and complete the walking and running protocols, each taking 1 minute, on the treadmill. * While walking at your normal walking speed, step so that your dominant leg is positioned over the force plate. * Repeat all of this for the insoles at the other two angles.
