The quality of these leather, handmade shoes is hands down some of the best I've seen. Genuine leather upper. Rubber sole. Ethically made. There isn't a pair I don't find comfortable. And no need to worry about leather blisters on the back of your heels. These sandals have been finished in a way that prevents the leather from rubbing on your bare skin and creating problems. 100% Wyld 'n Pretty approved!
