 After the participant put on the standard footwear no orthotic they will be set up with optotrak markers with three on the first ray, three on the midfoot, three on the heel, and three on the medial distal tibia. Then the participant will walk across a 10m walkway with a force plate embedded half way along the walkway at a constant velocity for a total of 15 trials. The participant will rate their pain on the visual analogue scale VAS immediately following the completion of the 15 walking trials.
