I wanted to try the mizuno wave alchemy 10 due to reviews that I had read. These shoes feal great. I can run in these and my feet feel nice and snug but they are not too tight or cramped. A great fit, stability is not too stiff. I love these shoes and I am so glad that I bought two pairs.  I usually wear a 7 1/2 and wear an 8 in these. Enough space for my toes. Feel broken in with first time wear. So comfy. I was hooked on Nike, but I am sold on these shoes.
