Rechargeable Heated Insoles

Unlike typical heated insoles that require clunky external battery packs and wires, these cordless insoles have embedded rechargeable batteries that deliver enough heat to keep feet at a comfortable 98.6° F for up to eight hours of skiing, sledding, or snowshoeing.

The wafer-thin lithium-ion cells are virtually undetectable and can be recharged up to 500 times with no battery "memory," ensuring a consistently lengthy operation with each use (requires eight-hour charge from AC adapter).

The insole's six-layer design includes a shock-absorbing, ergonomic polyurethane base while a layer of heat-retaining synthetic material staves off frigid temperatures.

Carrying pouch holds insoles and included lightweight recharging adapter.

Plugs into AC.
