I am a new restaurant owner who is on my feet 16-18 hours a day 5 days a week and 4-10 hours the remaining 2 days. I've had severe back pain for the past few weeks, which I thought my shoes were contributing to. An hour after I put these shoes on, mid-shift, my back stopped hurting. I feel taller and my posture improved immediately. Cons: They feel tighter than expected and my feet hurt from hard soles. But like most shoes, I expect them to stretch a bit. I've already noticed that they fit better now (day 3) but I'm worried about sore feet from the shoes. The time will show. Pain in the legs or in the back. should i choose
