Everything about socks
for men.
Care, size, wear: clear answers to the questions people ask about socks.
Three rules are enough to keep good socks for a long time: choose the size range that matches your shoe size, wash at 30 or 40 degrees, inside out and without fabric softener, and rotate several pairs. Most holes come from a size that is too small, toenails that are too long or heat when drying. The guides below cover each point in detail.
