The Lectra Sock was originally developed for commercial fishermen but has been reinvented with 1990s technology. The heat output has been increased and the wires and heating unit are now buried in recessed channels in the socks making them invisible to the wearer. A new wool blend has been formulated to provide increased warmth and maximum wicking.
The "D" size alkaline battery provides 4-6 hours of continuous heat, more when used intermittently. Safe and comfortable, the Lectra Socks works even when wet. The heating element is safely buried in a channel located in the toe area. Perfect for outdoor use for hunting, fishing, hiking and all other cold weather activities.
These socks are not designed to get extremely hot! They are designed to keep the feet warm thus making it more comfortable to be out in cold weather.
The heating element is safely buried in toe area. Invisible to the wearer, the heating element is designed to warm the toe cavity thus keeping toes and feet warm.
The socks can be used with rechargeable batteries and will provide shorter 2-3 hours of use.
