I'm not too picky when it comes to shoes; I just want something comfortable and soft when I work out. These are probably the worst shoes I've ever worn. The soles are so hard and flat it felt like walking barefoot on concrete. The walls surrounding my ankle are paper thin and rubbing my ankle causes bleeding. Also, my Achilles tendon was bleeding towards the end of the run. I wear low socks with all sneakers and have never had this problem. No wonder they sold for $40 lol.
