These socks as stated are VERY thin ...which is EXACTLY what I was looking for...the fit seemed perfect as well ...I ordered the 39-42 I think and I wear a 9 med....I have not washed and worn as its summer in Texas and only wear sandals then so can't speak about the way they might hold up ...but for this price if you only wore 2 or 3 times probably got your money's worth!
