I was looking for any black shoes that would still hold the style. These turned out perfect! They are very light and have firm but soft padding and support inside. I had no problem with them coming loose during the day. Some shoes keep coming loose. It's not like this. I usually wear women's size 9. I bought men's size 8 and they fit perfectly. They are easy to put on and very comfortable for my foot. The material is breathable. They have not lost their shape and have not stretched. I haven't done any "official" training in them. However, I walk a lot at work and my feet and legs feel good at the end of the day. I would recommend them. This is a great product at a great price. Thanks.
