The Lectra Sox are designed to keep feet warm, but not hot. Engage the heat only after you begin to feel cold. Maximum benefit will be obtained by turning the socks on and off often. Do not allow the feet to become overheated. Although not necessary, if you wish to wear two pair of socks, the socks next to the skin should be Lectra Sox. Great for winter sports, spectator sports, hikers, hunters, fisherman & seniors. Lectra Sox technology uses extremely low amperage thus eliminating all possibility of shock or burns, even when wet.
