"Took these on a 4-day ski trip in Vail, CO. Usually by 1 PM my toes are painfully frozen and I need a warming hut. With FireFootie, I skied first chair to last chair with zero discomfort."

Frequently Asked Questions

Everything you need to know about FireFootie Heated Insoles. Have questions?Contact US Support

How do I cut the insoles to fit my shoe size?

FireFootie features clearly marked trim lines along the toe perimeter supporting US shoe sizes 4 through 12.5. Simply take standard scissors and carefully cut along your designated size guide, or trace the factory insole from your favorite boot for a custom match.

How hot do the insoles get and what are the levels?

FireFootie offers three distinct heat presets: Low (~104°F) for all-day comfort, Medium (~122°F) for chilly outdoor walks, and High (~140°F) for extreme sub-zero weather and snow sports.

How does the smartphone APP control work?

The FireFootie app connects via wireless Bluetooth on both iOS and Android. It allows you to check battery levels, independently adjust temperature settings for each foot, and set 6 programmable auto-off timers without untying your boots.

How long does the 3000mAh battery last on a charge?

The built-in 3000mAh battery delivers up to 6 hours of continuous heat on lower settings and 3.5 to 4.5 hours on higher settings. Recharging is quick and easy using the included 5V 2A USB cable.

Are the insoles waterproof and safe for wet snow?

Yes! FireFootie is built with waterproof construction, engineered to withstand sweat, slush, melting snow, and brief exposure to wet conditions safely and comfortably.

Will they make my footwear feel tight or cramped?

Not at all. With an ultra-slim profile of only 0.19 inches, FireFootie is as thin as a standard high-performance athletic insole. It slides easily into work boots, ski boots, trail runners, and everyday sneakers.

What are your shipping and return policies?

We offer fast and free standard shipping on all US orders, typically arriving within 3–5 business days. Every order is backed by our 30-day risk-free money-back guarantee.
