text: Bought these primarily for the arch support - and they have been wonderful!  I am currently in my 3rd trimester and badly needed something to ease the foot pain I was having.  I could no longer go barefoot in the house and didn't want to constantly wear my sneakers when at home.  I did see other reviews that said they can run a little small but since I have a more narrow foot, size 7, I decided to still go with 6.5-7.5 size.  At first I was a little concerned because they squeezed my toes when I first put them on but after about a day they had adjusted.  I think if I had gone with the next size up they would have been too big around the heel.  The fake fur can be a little warm during the summer so I only wear them when I'm actually up on my feet and I take them off when I sit down - but it's worth it for the arch support and they are very soft and comfortable.  During the winter months I expect I will be able to wear them for longer periods of time.  I would recommend choosing a size with toe and heel width considered as well as foot length.
