I have ordered these socks for my son was a bit skeptical about the "One size fits all" was concerned. My son has shoe size 42 and the socks fit comfortably, do not slip and also do not interfere with the sutures well. I remembered well the socks in the new state had a very chemical smell, after the first wash at 40 degrees and a dip in the dryer, however, this was removed and the socks have retained their shape and size. My son complained that the socks have all the tiny colorful Püncktchen, they look like colorful peeling Fuselchen which are solid processes in the material that could not be identified on the product page. In my opinion there are only socks.
Conclusion: A star is deducted because of the chemical smell and the colorful Fuselchen.
