HOTRONIC’s S4+ Series Foot Warmers offer more than ever before. With enhanced reliability and longevity, the S Series NiMH batteries maintain up to 55 % of a full charge and 95 % of their initial capacity after four years of non-use! Plus, an increase in capacity offers up to a combined 30 % in higher average temperatures and longer durations on a single full charge, all when needed most, in the cold!
By blocking and neutralizing the penetrating cold, HOTRONIC’s Heating Element keeps the blood circulation open while maintaining comfort and warmth in the feet. The Heating Element’s large oval shape and self-adhesive backing provide effective anatomical coverage of the toes and easily install in HOTRONIC’s Heat Ready Insoles or on insoles of one’s own choice.
