Awesome and stylish shoe!
Size: 12, Color: Brown
What a great shoe, especially for the price. Feels very comfortable on my feet. Only wore them on one occasion so far, but had them on all day and they felt great and didn't get any blisters. The shoe looks WAY more expensive than it is. Great shoe from a great brand!
