I found out the fault and problem with one sock. But when two socks in the same box had holes in the same place on the side, I have big doubts about 1) the quality of the manufacturing process and 2) the durability of the material. Also, I have US men's shoes in size 10.5. I bought the largest size they are (9.5-12.5) and I can't imagine them fitting my foot even if I was half a size bigger. They were very comfortable. Added a second star because I liked the design and minimal packaging (very little waste) but will look elsewhere for quality cycling socks.
