The A Cold Wall x Converse Sponge CX Crater (A02613C) is a combination of futuristic style and modern comfort. With this, A-COLD-WALL gives a new twist to a new model from Converse. The ultra comfortable Converse Sponge Crater actually consists of 2 parts, the Crater foam body and the flat knitted upper. Both contribute to the overall comfort of the shoe and encourage the 'less-is-more' aesthetic.
