If you are looking for a size for big feet like me I'd suggest trying an actual asain market that sells these kind of shoes. These shoes are meant for actual size 10 in US feet due to the 1 inch toe room from the front edge. I think they measured the entire shoe which is about 11 inches, but more like 10 inches from where the toes actually started. I would typically just fit a size 11 shoe, but normally I get size 12 just in case I need the foot room. The straps are also going to be very tight so I do not know anything on wear and tear there or if they will fall apart overy time. I'm just going to stick to flip flops until I find an actual shoe store that has one of these in the US.
