Clyde's X1 Popper is a new super thin and light weight composite shoe insert developed in cooperation with a leading Sports Medicine clinic in Indianapolis, IN. The "Popper" maintains just enough rigidity while adding a slight velocity pop at the end of the gait cycle to ease mild bunion pain and encourage a more normal gait. The X1 "Popper" will fit in any shoe, and because it is so thin only requires the use of one. The X1 Blade Popper retails for $79.95 ea.
