Got this shoe to replace my pair of Alchemy 10 that I bought a couple of years ago cause I needed new activity shoes and I liked how they looked (that's it) :) Since then I've gotten into running and my old size 9 (I usually wear 8.5 or 9) started giving me blisters and hurting my heal BAD. I did some research and tests and realized that Alchemy was all a wrong shoe for me to begin with and that I needed a size bigger to give my toes some room to move :) Creation 12s were the right fit for my arch and heal. Took them out running twice now and I L-O-V-E them! No blisters, NO HEAL PAIN if I run up or down hill. I thought I liked my Alchemys, but Creations are heaven for my feet :) Do your research and try them on at the store before you buy online.
