I love the slick outlook of the kicks! However, after I took them for a first walk outside, my heels were covered in blisters. It seems that the heel bends a little towards the inside of the shoe. Now Im not able to return them anymore, so Im trying to stretch the heel by wearing them inside. Would maybe recommend ordering 1 size bigger to prevent the possible friction.. The fast delivery service was awesome! Ordered the shoes in the morning, received them in the afternoon!
