I bought these in grey for my mother who has thick, wide, flat feet.  She was having heel pains so I thought these would help and she confirmed that her feet do feel better.  She said they are very comfortable and if mom likes them, I like them.  There is good arch support and the flip flops are not too stiff.  Mom likes that the thong between the toes is made of fabric and doesn't hurt when walking. She's been wearing them every day this summer.
