These shoes are fantastic for walking; for sprinters or runners where speed is a concern, however, best you opt for something more traditional, something with a fastening mechanism. Wish that they came in different widths. I hate shoes without arch support and need a structured shoe. I had a couple of pairs years ago. I would recommend ?? Also comes with a Samsung brand wireless charger, which it works great with no problems. Was turned on to this release by Oluvs early review. No complaints at all. UPDATE: Ive been using this for a while now and its still flawless. So Reef if you are listening you will never sell me any more Chinese crap
