The "COOL KICK INVISIBLE" short socks are a cut version of the classic "RUN" socks. They have a snug fit that covers the top of the foot, making them perfect for sneakers. The anti-slip feature on the heel prevents slippage while wearing. Size 37-38: Equivalent to Japanese sizes 23-24.5cm Images 1 and 2 are reference images. The items for sale are a set of 3, one each in Grey, Black, and Marine. Marine appears to be a dark navy. All are new, only opened, and stored in a drawer. They haven't been used because I haven't had the opportunity. There are some slight frays and small pills, possibly from storage. The grey ones have a slight fuzziness. Please purchase directly. I may not be able to reply to comments immediately as I work full-time. I cannot provide photos of the socks being worn, sell them individually, negotiate prices, or offer gift wrapping. I will not respond to price reduction comments and will delete them later. I do not offer holds or reserved listings. I will prioritize the first person to purchase, even if there are comments in progress. Depending on the timing, shipping may take a few days as I live in the countryside and work. Please refrain from purchasing if you need them urgently. I ship about 3 times a week. COOL KICK INVISIBLE Women's Men's Unisex Ankle Socks Non-slip Black Grey Cool Kick
