At first, these shoes were extremely painful to wear, causing blisters on the heel. The leather, however, stretched after about a week and now they're my most comfortable flats! The leather on the outside is artfully crafted to appear like scales, be careful when wearing these while driving however as the leather on the back of the heel will begin to wear from repeatedly using the gas pedal. I will definitely be getting another pair of a different color! These are essential for any wardrobe!
