NikeLab ACG 07 KMTR 'Cool Grey'

The design impetus for the NikeLab ACG 07 KMTR began with a paper bag over a foot, scrunched to form the shape of a shoe. That simple concept would lead to a silhouette that uses a single-piece, water-resistant upper with four-way stretch. It conforms to the foot by pulling on an integrated drawcord, with a forefoot strap included for added stability. The Cool Grey upper is supported underfoot by a matching full-rubber sole unit with wet traction lugs.
