Product Description


Hotronic FootWarmer Power Plus S4 Power Set

The Hotronic FootWarmer Power Plus S4 Power Set includes everything you need to boost your battery capacity for Hotronic's pre-wired BD Anatomic Insoles or for any other insole of your choice installed with Hotronic's Heating Elements. The Hotronic FootWarmer S4 Power Set operates off of 4 high-capacity, cold-temperature-operation, rechargeable NiMH AA cells. This gives you the best variable temperature-setting duration of any Hotronic warming system out there! Upgrade your S3, e, or m series battery pack to a FootWarmer S4 Power Set for longer lasting warmth and make the most of those frigid days this winter. We also carry the entire line of Hotronic Products!
