THE BEST PERFORMANCE CUSHIONING
We chose Poron^® Cellular Urethane for the most crucial forefoot & heel areas as we believe it is the best insole cushioning material available.  Poron is light weight & durable, it does not harden like PVC foam, does not break down like Latex foam or take a compression set like EVA foam.  The anatomically shaped extra deep heel cup and arch match the ideal contour of the human foot, maximizing contact with the surface area of the insole and spreading the body's weight over a greater surface area.  This feature effectively increases cushioning by reducing Peak G Forces & pressure.

ADVANCED FIT SYSTEM
Our tapered toe design provides the appropriate amount of room in the toe box of the shoe. To insure the foot fits properly inside the shoe, the heel & forefoot thickness of the SL Insoles have been adjusted by size. For example; a Women's size 6 insole is for a smaller foot, so it's made proportionately thinner in the heel & forefoot than the larger Men's size 13 insole. Our separate Men's & Women's insole sizing allows us to make a better fitting insole for Men & Women.
