CRISPI ALTITUDE GTX 8" BOOTS - ANTHRACITEThe CRISPI Altitude was designed and built with a desire to combine a breathable and technical fitting upper with the long lasting comfort of the EFX dual density midsole. This combination gives hunters the reliability they can count on when long miles and the occasional heavy load is expected. A constant and even flexing board last (Flex 2. 5 rating) and our exclusive CRISPI Vibram Megagrip outsole, make traversing variable terrain a breeze. Features
