KEEN UNEEK Sandals 14,300 yen Color: Black UNEEK is an Open Air Sneaker. A next-generation sneaker made from two cords and a single sole. This revolutionary and unique hybrid footwear was created after rethinking the way shoes are made from scratch, and took three and a half years to develop. With Socks: By changing the combination from thin socks to fleece socks, it can be worn for three seasons. I wore them with socks until early autumn. After use, I washed them with water and dried them thoroughly before storing them.
