Abstract:
1. A method of using a shoe system having a progressively resilient shoe insert, comprising: providing a shoe-insert having an upper leg and a lower leg connected by a front end, providing the upper leg with an upwardly-facing concave front segment and an upwardly-facing convex rear segment terminating at the front end, providing the lower leg with a downwardly-facing concave front segment and a downwardly-facing convex rear segment, the lower leg forming a mirror-image of the upper leg, putting a first load (L the first load (L pulling an upper forward segment away from a lower forward segment immediately adjacent to the front end and creating a first loop opening, the first loop opening being defined by the upper forward segment, the lower forward segment, the contact area and the front end connected to the upper forward segment and the lower forward segment, progressively increasing the first load (L the upper forward segment and the lower forward segment expanding the first loop opening to a second loop opening, the second loop opening being defined by the upper forward segment, the lower forward segment, the contact area and the front end connected to the upper forward segment and the lower forward segment, progressively increasing the second load (L the upper forward segment and the lower forward segment expanding the second loop opening to a third loop opening, the third loop opening being defined by the upper forward segment, the lower forward segment, the contact area and the front end connected to the upper forward segment and the lower forward segment.
