These are a blessing to anyone who suffers from cold feet. I have spent many years with frozen feet in very cold places and opted for these when still living in the Alps but left before needing them in the winter. They may need new lithium batteries (the typical estimated life of a lithium-ion battery is about 2-3 years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged to fully discharged and fully recharged again).
