I purchased these shoes several months ago. At first they were fine, took awhile to get my balance right, felt a bit too bouncy going down stairs, like I was vaulting forward. Unfortunately I wore these shoes daily. Easy tone shifts the weight onto your heel, now I can barely walk without shoes on, the pain in my heels is almost unbearable. If you do buy this shoe, I guess only wear them to work out. I have taken a week off work, went barefoot for that week, but it feels no better, my heels are still on fire! Good luck!
