I initially love the shoes because it feels very comfortable when you put it on. No break in period at all. I used it this morning for the first time for about 2 hrs to the grocery and to run some errands but when I got home I have pain on my left heel. I tried not to walk so much to rest my left foot but everytime I stand up my left foot hurts making it difficult to walk. I hope I don't end up with plantar fasciitis. This shoes has absolutely no support at all so I'm returning it back. I normally wear size 7.5 and size 8 fits me.
