I bought these shoes in July 2021 it is now late September 2021 and although these shoes started well they wore out quickly. When I first received them they seemed a little tight and I thought they needed a little wear to be comfortable and after being broken for a while. I usually walk about 10,000 steps every day as I enjoy it more than cardio running. These have been my daily drivers since I've had them but at the end of month 3 the back of the collar has outlived their usefulness these shoes already look like I've had them for years. Because the back of the collar is worn, they are very uncomfortable and hurt the back of the heels. Before that I had a Pegasus 35 and loved these shoes which I have owned for many years and to be honest they were my favorite shoes. I am very disappointed in this.
