RAINPROOF. By 1970, the design of the Chuck had evolved to the height of function and utility for sport and was considered the best basketball sneaker, ever. This waterproof Chuck 70 is built from that original design, with extraordinary attention to detail. Premium GORE-TEX materials block out the rain. Can’t forget the archival rubber taping and extra cushioning. That’s the Chuck 70. And it’s ready to take on the elements.
