This is the 5th collaboration item between Snow Peak and TOKYO DESIGN STUDIO New Balance, a set of snow boots and room shoes. The inner boots can be removed from the outer shell and used as room shoes. The size is 26cm, but due to the inner boots, I believe it would be a suitable size for someone around 23cm as well. The sticker on the box is for a different size, but the product is 26cm. We kindly ask that you check our profile before inquiring or purchasing.
