HOW FEET BECOME COLD

HOW FEET BECOME COLDWhen colder outside temperatures are detected, the nervous system restricts blood flow to the extremities to maintain the body’s core temperatures. The toes (and other extremities) quickly become uncomfortably cold.

HOTRONIC KEEPS FEET WARM

HOTRONIC KEEPS FEET WARMBy providing a base level temperature at the toes, Hotronic’s Heating Element blocks and neutralizes the penetrating cold keeping the blood circulation open while maintaining comfort and warmth in the feet.

Hotronic’s S Series Foot Warmers offer three (3) base level settings for comfort and warmth maintenance while Boost Setting 4 offers an extra blast of heat when needed.

WHEREVER YOU GO

Whether planning a brief outing or a long term journey, Hotronic’s Foot Warmer S4 is easy to use in all types of footwear. Use while skiing, snowboarding, bicycling, horseback riding, fishing, and during other coldtemperature activities.

POWER MULTIPLIED

With four (4) batteries in each Battery Pack, the Foot Warmer Power Plus S4 is Hotronic’s longest lasting, most powerful Foot Warmer. At the same time, Hotronic’s NiMH batteries do not have a “memory effect” and do not require fully discharging before fully recharging. Hotronic’s S Series Recharger and Heating Elements come standard with each Foot Warmer S4.

AN ELEMENT OF HEAT

AN ELEMENT OF HEATBy 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 selfadhesive backing provide effective anatomical coverage of the toes and easily installs in Hotronic’s Heat Ready Insoles or on insoles of one’s own choice.

SET FOR COMFORT & WARMTH

The Foot Warmer S4 offers three base level settings for comfort and warmth maintenance. A fourth setting offers an extra blast of heat when needed. Press-hold-and-release the Battery Pack’s ON or OFF button to select the desired setting. Easy to read LED lights indicate the setting selected and when the power is on or off.
