Highest comfort and optimum heat distribution.
The BOOTDOC Power Fit Socks with integrated heating elements combine excellent comfort, perfect fit and optimum heat distribution. Simply attach the high-performance lithium-ion battery packs to the heated socks with the snap fasteners on the inner side of the cuffs and regulate the 4 levels of heating output directly on the battery pack. The power boost setting provides a short period of extra warmth. A major benefit is that the battery packs can be combined with HOTRONIC heated insoles from the XLP series.
