I really wanted to like these shoes! First off they were difficult to put on because there are no laces. They felt comfortable and fit nice. Once on and worn for a 3 mile walk, I had blisters on my heels, on the inside and outside of my small toes. Ouch! I still wanted to like them, so I thought maybe I needed to break them in. I wore them on a hike to Lake Superior because of the sandy-rocky shore. Again my heel bleed from rubbing. In the water, sand passed into my shoe so I had a sand dune of wet sand to rinse out when I had to hike back. No way would another size work because the shoes were already difficult to put on. I would never recommend a friend to buy these! Painful, useless but pretty!
