Please review the profile before purchasing! ASTEN's five-finger design sports compression socks, made of elastic fabric, are perfect for training and matches. Color: Navy, 2 pairs Size: S (22cm - 24cm) Although they haven't been worn much, baseball is a strenuous sport, so even after only one or two uses, there may be some dirt or fuzz! Are you interested if you understand this? The retail price is high, so are you worried about buying them or whether they'll fit your child? Why not try buying them as a trial? By the way, here's what my child said after using them: "They definitely make it less tiring." "But they're hard to take on and off!" Maybe even more so because I bought them in the summer... My child didn't continue wearing them because of the inconvenience of taking them on and off... Thank you for looking.
