I wear a size 12 in womens. I have long toes and high arches. Im a pediatrists dream come true and just finding a shoe that fits is an adventure. I was a bit apprehensive to order these online but they were such a good deal I went for it. Holy smokes. They fit so well!  I went running on the trail near my home as soon as I got them. My dog had trouble keeping up with me. They were so comfortable I put them back on and went to work with them. No new show pain whatsoever here.
