I wear a 7.5 M normally, but based on other customer reviews, I bought the size 8 M. Although they were very cushiony, I felt they were extremely wide and a just a little long. So, I ordered the 7.5 M. This pair was the right width, but they were just short enough that my big toe brushed against the front. I decided to keep the 8 M. Better to have them a little too big than to have my toe bumping up against the inside stitching. In hindsight, I should have returned both pairs, but I am having a tough time finding any sneakers with a good arch support for my high arches, and I needed something.<br />After wearing them a couple of months (frequent usage), I developed a great deal of pain in my hip and thigh, so much so that I considered getting an x-ray. I stopped wearing them for a week, and all the pain is gone. Clearly, these shoes do not provide the correct support. It could simply be that I just never had a good fit seeing as they were so terribly wide. Perhaps it's the fact that they have so much bounce to them, too much for prolonged wear. It's a shame because they are very cute in person. These will be donated as they are of no value to me anymore.
