Pinfect 3Pairs Winter Heated Socks Anti-Fatigue Multifunctional Thermal Sock for Hiking (black)

Warm Tip: 1. The heat energy caused by too long use or improper maintenance cannot be released. Please put the hot socks in the sun to recover. 2. Hot socks need to be washed by hand and quickly. They should not be soaked in water for a long time (to prevent hot spots from being damaged). They should be washed with flowing warm water and should not use detergents.
