I love these shoes. They are my "instant" slip on shoes. In fact I love them so much that I will probably end up with one in every color. I have feet that blister. Bad blisters, and not due to not wearing the right socks blisters, an inheired genetic thing that runs thru the family thing. Anyway, these shoes do not cause blisters!! They fit true to size, look great, and wear forever!! You can't go wrong with these shoes. I wear a 6 and have a high arch and these shoes fit perfectly.
