Cold feet warm heart?  Who ever heard of that?  exo² The Heat Inside is pleased to bring you the HeatSole Heated Insole.  We’ve taken the complexity out of using heated insoles and offer an effective, no non-sense approach to keeping your feet warm when Mother Nature is not playing fair.  Each HeatSole comes with an individual lithium-ion power pack that delivers 5-7 hours of continuous heat per charge.  Each top quality leather HeatSole is cut to size and one size fits most. The integrated FabRoc™ heat panels self-regulate at approximately 113° F for ideal comfort, regardless of the shoe, boot, or ambient temperature.  HeatSoles are ideal for skiing, hiking, motorcycling, fishing, riding, hunting and all who struggle with poor circulation.   A Velcro strap for clipping the power pack to lower leg (if not wearing a boot) is provided to conceal the tiny power packs from view.  Warm feet, warm heart.  Doesn’t that sound better?
