Montbell Sock-On Sandals Color: Black (BK) Size: S (23.5-24.5cm) Official Description: This model features Montbell's unique S-shaped thong, allowing you to wear it even with socks on. The thong that directly touches the instep uses a material that is gentle on the skin. It combines an open feel with excellent hold, making it easy to wear for camping or everyday use. Purchased at a Montbell store one year ago. Used twice, and as the photos show, there is almost no wear and tear (cleaned). However, this is a used item, so please refrain from purchasing if you are concerned about minor details.
