These are the patented athletic shoes with a compartment that conceals a removable cartridge for stowing credit cards, cash, and keys, letting you hike, sightsee, or work out unencumbered by a wallet or fanny pack. Hidden in the midsole of the left shoe where it will not affect the shoes support, comfort, or flexibility, the cartridge clasps items tightly so you wont hear any rattling as you walk. The shoes have a durable non-marking rubber sole that provides long tread wear and sure traction, and up to 1 1/2" of lightweight phylon cushioning in the midsole. The phylon and polyurethane insoles have EVA heel pads that provide additional cushioning. The uppers are made from a breathable nylon mesh that helps keep your feet cool and dry. White or Black. Mens sizes 6-13, whole sizes only (women order one size down; half sizes order next largest size). (3 lbs.)
