Socks are designed for sports use and some are geared towards the use in hockey skates. Most are thinner by design as it gives you a closer skate to foot feel, which aids in performance and comfort. Some will have moisture wicking technology or antimicrobial properties to decrease the bacteria growth and help in drying time. Also, some socks are knee high while other go to your mid calf. Choosing the right pair of socks is your own personal preference.
