BootDoc Heat Socks Set

A sock set consists of a pair of BootDoc Power Fit Socks with integrated heating elements and powerful lithium-ion battery packs with a charger. The charger has plugs for both US and EU use. 

The unique performance of BootDoc Power Fit Socks with integrated heating elements ensures excellent comfort, fit and heat distribution. The battery packs are easy to connect with the snap fasteners on the inner cuff of the heated socks. The 4 heating levels are selected directly on the battery pack. The Power Boost setting provides extra warmth for a short period (approx. 3 minutes). 

Battery power varies based on temperatures and settings used. You can expect to get 2 - 8 hours out of a charge. The lower the outside temperature and higher the setting you use, the shorter the charge will last. Most people will use setting 2 on a regular basis in ski boots. Setting 2 will generally last "all day" (4 - 6 hours) depending on the temperature outside.

These heated socks are thinner than some of the others on the market and offer a "true ski sock fit". The nylon/wool/spandex blend is durable and holds it's shape well for years of use. They offer soft compression of PFI 50 for the ultimate in performance and warmth - even in a plug race boot!

Make sure to fully charge your batteries according to the direction before first use.

To wash, remove the batteries, turn the socks inside out, put them in the mesh bag provided, throw them in the washer (max water temp 30°C/86°F)! Lay flat to dry.

They help me stay outside longer in winter.
I LOVE my BootDoc heated socks. They enable me to stay outside longer and enjoy myself doing the things I like to do. I wear them skiing, snowboarding, winter hiking and snow shoeing, ice skating, sledding, white water kayaking (under my dry suit), late fall cycling, standing around watching my nieces and nephews sports name it. Thanks to my heated socks I am warm and comfortable. I have both the Lenz and the BootDoc heated socks and find the BootDoc socks to be thinner, more fitted and hold their shape longer (more like a true ski sock). They never stretch/loosen up after prolonged wear and sag and create pressure points in my ski/snowboard boots - as my Lenz have done - after multiple days of wear without washing them).
