This study aims to directly compare traditional everyday activity shoes (ASICS, Nike) with a shoe created to be flatter, less cushioned, and with less cradling of the foot (OESH shoe).
This study addresses a common question in popular media: what attributes of traditional everyday activity shoes (Nike, New Balance, etc.) make a shoe better or worse. There have been several peer-reviewed studies aimed to answer this by calculating forces and torques at the ankles, knees, and hips while subjects wore shoes with different properties. Such characteristics include heel size, cushioning and side-to-side cradling of the foot. Interestingly, most studies have shown that the lack of a heel, less cushioning, and less cradling of the foot actually improve the biomechanics related to forces and torques, thus decreasing wear and tear on the cartilage and bones of the leg. Wear and tear on cartilage and bone may predispose patients to a bone condition called "osteoarthritis", which is a disease where bones become damaged from rubbing on each other with breakdown of a cartilage "cushion". This study thus aims to directly compare traditional everyday activity shoes (ASICS, Nike) with a shoe created to be flatter, less cushioned, and with less cradling of the foot (OESH shoe).

| Evaluation | Other | Subjects will be asked to walk across the gait laboratory floor at their self-selected walking speed. They will complete a 3-5 minute warm up period, as it was found to produce stable estimates of kinetic parameter mean values during treadmill activity. The positions of each marker will be recorded through the motion capture system. Ground reaction force will be obtained in real time from the gait laboratory force plates as marker dimensions are recorded. For walking data, two trials of 15 seconds each will be recorded. The second trial will be a redundancy in the setting of potential significant marker dropout. |

| Differences in torques at the knee comparing three study arms | Joint torques and forces will be assessed via 16 markers placed on specified anatomical landmarks of the pelvis and lower extremities as the subjects walk across the gait floor at a self-selected speed. In analysis, joint torques and forces will be calculated through full inverse-dynamic model implementation using the Vicon Plug-In Gait. Differences in torques and peak forces will be calculated by ANOVA along with 95% confidence intervals. | One-time at enrollment, no follow-up |
