ThermaCELL Proflex Heavy Duty Heated Insoles

Slip Thermacell's Proflex Heavy Duty Heated Insoles into your hiking shoes, ski boots, or casual sneakers, and then use your smartphone to adjust the insoles' heat for customized warmth throughout winter. Their batteries last for eight and a half hours until they need a recharge, which only takes two hours for a full charge, and you can recharge them five hundred times for long lasting use. The Poron foam surrounding the removable batteries is shock absorbent, odor resistant, cushy, and flexible for free moving comfort, and you can trim them to fit your shoes perfectly. Thermacell included a smart charging case, wall charger, USB cable, and travel bag with the insoles and batteries.
