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 creation of 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 lightweight recharging adapter. Plugs into AC. Sizes S (Men's 4 1/2-5 1/2; Women's 6-7), M (Men's 6-7; Women's 7 1/2-8 1/2), L (Men's 7 1/2-8 1/2; Women's 9-10), or XL (Men's 9-10 1/2 ; Women's 10 1/2-12). (1 lb.)
