Bought two pair of these, one for me and one for my mother. She has problems with swelling and could not get the shoes on. My pair worked great. There is not much give around the shoe opening, so those with swelling problems should not buy these.
I love wearing them to work, I walk a lot around campus (7 buildings) and perfect for the summer (because I don't have to wear socks) - the shoes breathe. I love memory foam because the material offers a lightweight yet firm support to my foot! I never feel tired and I enjoy walking!
