I wear a US size 9-9.5, so I ordered a size 9 (41), and the sandal stuck out 1 inch past by toes, and was too tight over my ankle. The design of the sandal was also not as advertise = the buckled straps are not actually full straps. There are hooks on the shoe, and the straps are not attached to the shoe/sandal back. You're just supposed to slip the loose straps in the hook, and expect it to stay when you are walking. Which it does NOT. See attached photos. I dislike negative reviews, but I put these right back into the box after I opened them.
