I really like these shoes. If I have the option I prefer a wide shoe but I bought these in an 8.5 M which I wear when I cannot find a wide shoe. They fit perfectly. I wore them one whole day the first time I wore them. I took another pair of shoes with me to change but never had to change they were so comfortable. I also have a bad back and need to watch the heel size I buy so I was leery when I ordered these. I have no back pain when I wear these shoes. I would not hesitate to recommend these shoes and I would buy another shoe from Miz Mooz based on these shoes.
