Item detailsMaterials, dimensions, what is in the box
Heated shoe inserts with EVA foam and carbon-fiber heating wire add warmth inside your footwear during winter. These black heated shoe insoles have white curved trimming guides and come in size ranges 35–40 and 41–46. Choose the range that matches your footwear before using the guides to adjust the fit.
The USB heated insoles connect through a USB-A cable with split leads, bringing power to both inserts from one connection. Illustrated power sources include a USB wall adapter, computer, laptop or portable power bank. The package brings together the pair of insoles and its connecting cable, so you can combine them with your own external power source.
Use these electric heated insoles for winter foot warming during activities such as skiing, climbing, cycling, fishing, playing in the snow or outdoor work. Their layered construction includes nylon, carbon fiber, EVA and a rubber heating pad. The 41–46 option has a stated thickness of approximately 0.16 inch, a useful measurement when considering the space inside your footwear.

What problem does it solve?
Add warmth underfoot when winter activities leave your feet feeling cold inside your footwear. These heated foot inserts put a powered warming layer inside your shoes rather than adding another item to carry in your hands. They suit outdoor work and seasonal activities, including fishing, cycling and time spent playing in the snow.
The problem in numbers
In 2023, 1,024 US deaths were attributed to excessive cold or hypothermia. (Centers for Disease Control and Prevention, QuickStats, 2025)
January accounted for 19.9% of US deaths attributed to excessive cold or hypothermia in 2023. (Centers for Disease Control and Prevention, QuickStats, 2025)
In 2020, US private-industry workers experienced 190 environmental-cold exposure cases that required at least one day away from work. (US Bureau of Labor Statistics, 2023)
Cold-weather activities call for appropriate clothing and sensible exposure limits. These USB-powered inserts add warmth inside footwear, but they are not protective equipment against hypothermia or cold-related injury.
Why choose this one?
Choose them for the combination of EVA foam, carbon-fiber heating wire and a cable that connects both inserts to one USB-A input. The white curved trimming guides help you adjust their outline within your selected size range. These heated sole inserts offer a straightforward wired setup that works with an external USB power source.
