Unorthodox Y-3 trainers with a snug knit upper.

The Y-3 Kyasu Slip-On skews conventional design and focuses instead on minimalist expression. Without using any glue or lining, the tooling is crafted with a one-piece polyurethane build, with the engineered adidas PRIMEKNIT upper stitched onto the irregular, concrete-like structure. The result is a completely raw interpretation of a shoe that slips onto the foot with a sock-like fit.
