The first pair I ordered were way too big. I sent them back. But I did like the style, so later on I ordered a pair a half-size smaller. I would have gone a full size, but there wasn't one available. I have been able to wear these, they are a little long, but they stretch in width comfortable. I have slip room fore and aft. The smaller size would have been a better fit. The heel...don't plan on doing a lot of walking in them unless you know your shoe repair shop well. The thin rubber will quickly wear into the midsole, and then it gets expensive to fix.
