This is a set of three items: Montbell Sawatabi 26cm, waterproof split-toe socks M, and underwater knee support L. I purchased these new at a store and used them once for river trekking. The Sawatabi has one stain (photo 5), but otherwise, the condition is good. My usual shoe size is 25cm. - Brand: mont-bell - Model: Keiryu Shoes (渓流靴) - Color: Blue/Gray - Use: Outdoor activities Thank you for looking.
