These are FitFlop Lulu leather toe-post sandals in black, size 10. The size tag is unreadable, but I wear size 10-10.5, and in the pictures you can see how they fit me. I wouldn't recommend for someone with a really thin foot because the strap would be loose, and not give you a snug fit. - Softly padded uppers - Crafted in supple leather - Ultra-comfortable Microwobbleboard midsoles, regularly likened to walking on clouds. - Slip-on - Slip-resistant rubber soles These shoes have been granted the APMA* Seal of Acceptance, for footwear found to promote good foot health *American Podiatric Medical Association
