Add our best dual density cushy insoles to any shoe, and go farther. A unique blend of shock-absorbing materials feels cushy and stays cushy. A pattern under the forefoot creates an energetic springy feeling with every step, without sacrificing feel. Then our proprietary honeycomb heel cushion provides the highest degree of energy absorption and protection from impacts. Plush bands act to increase arch support. - Full length PU foam that doesn't harden over time. - A second, higher-density shock absorption pad protects your heel. - Whole sizing allows a much better experience over "cut-to-fit" insoles For half sizes we recommend buying up a size (ie: size 8 1/2 would order size 9)
