I bought both a 7.5 M and 7. W to try since many reviews said the medium ran wide. They do seem to be wider than most medium width shoes, but they were still a hair to snug for me. I was worried the straps would bite into me before they softened up.

I tried the wide width and for me it was more comfortable (gave me some wiggle room). However as someone I think might have stated the heel strap is much to wide. I considered having the straps shortened but I was not sure I would be able t find a place that could do it and also secure a ride before the return period. Hence they are being returned. If I can set something up in advance I may consider buying again as long as I am sure I can get the straps adjusted. But stars off for being TOO wide.
