I've only worn these once. They've been around for a while since I bought them, so there is some aging. I do not accept returns, so please ask any questions you have until you are satisfied! There is no box, so I plan to ship them in a paper bag. Please consult with me about the packaging method before purchasing! I wore a 22.5cm size. The heel fits, but there's extra space in the toes. The straps are Velcro, so they are securely fastened, and I personally didn't find them difficult to walk in. Color: Blue系 (Blue-based)
