This is my first pair of Adidas shoes. I liked the style of the all black with the 3 white slanted lines. I don’t like loud shoes and these were perfect as far as styling. The first pair I got were size 10. I wear a size 10 in everything. Even my Adidas boxing boots are size 10. When I tried them on they felt like they were going to come off at the heal when walking. I then exchanged them for a size 9.5. Same thing. I am hoping as they wear the slipping of the heal will stop.
