Kalso Earth Shoe clogs in women’s size 9, eu40. Purchased last fall and only wore one time. These are very high quality clogs with a strap that can either go on top of the shoe for slide on ease or conversely the strap can be used behind your heel for more a secure fit. Earth shoes have a negative heel configuration so your heel is a little bit lower than your toes. These clogs have a rubber section incorporated into the soles to assist in the flexibility of the wooden sole. Decorative metal tacks add to the vintage vibe.
