EVA or ethylene vinyl acetate is a great material for footwear because it is essentially waterproof and durable. It has been used more for clogs and sandal type footwear but Crosskix is looking to create an athletic shoe, and has looked to Kickstarter to “kix” things out.
The Crosskix aren’t meant to replace team sport shoes where cleats are worn, but could be good as a light training shoe, and certainly as a post-workout recovery shoe. If these get dirty there is no problem, as these are made of EVA the Crosskix can be hosed off and are ready to wear. Video after the jump
