Based on measurements and size chart these are a Large 7.5-8.5. Based on my faulty memory I believe they are a size 8. Please see pictures for conditon and ask questions if you need more information, I'm happy to help! These are an older style of Rainbow Sandals that no longer seem to be in production. They have a thinner sole (approximately 1/4 inch) in the ball/toe area of the shoe than the Classic sandals. The strap is also slightly thinner and the piece between the toes is leather instead of nylon. The heel is approximately 7/8 of an inch high, which is about 1/4 inch higher than the Classic sandals. As shown, the left sandal toe piece is starting to pull out. It still seems pretty secure, but idk how long it will last. I looked into the guarantee, and they might be covered for repair/replacement, but I'm not sure.
