I love the comfort of my new Fit Flops, but I wish I had ordered a size smaller. I read the other reviews that said they ran big, but having a wide foot, with a high instep, I decided to go for my regular size. They aren't huge, mostly just long at the toe - but I have short toes, so... I do love them and wear them all the time. I had a bilateral knee replacement 3 months ago and they are easy on the knees as well as the feet. I think they have improved the way I walk which helps both knees and feet. I have arthritis in my back and I haven't noticed a huge improvement with that, but maybe in time I will. I would definitely recommend them!
