Very good support and I feel that if I had ordered my normal size of 9 M that they would have fit. I ordered one size up, a 10 M because most of the other reviews said that they ran small but I don't feel that it would have been the case with me. I ordered natural because it was less expensive in my size than the other colors and it has worked out well for me because I am only using them for house slippers. If I had to list a con it would be that I wish they had softer insoles.
