I used to end ski days early with numb toes by lunchtime. With ThermoStride I'm first chair to last chair, warm the whole time. Night and day difference for my boots.

How It Works
How It Works
- Trim the insoles along the marked size guides to match your boots, staying clear of the heating panel
- Slip them in and power on — ultra-thin carbon panels under your toes and forefoot start radiating heat exactly where circulation fails first
- Pick low, medium, or high with the onboard button or app, and keep steady warmth for hours without ever stopping to adjust

What our 17,000+ Customers say
Based On Real and Honest Experiences
Contractor here, on job sites in the snow all winter. ThermoStride stays warm for 6-8 hours and honestly changed how I get through a shift. Worth every penny.
Angela K.Verified Buyer
Skeptical about app-controlled insoles at first, but an 8-hour ice-fishing trip proved it. ThermoStride kept my feet warm the entire time and it feels completely natural.

Q1 How many hours will these run on one charge?
On high (140°F) expect about 3 hours; medium (120°F) runs roughly 5 hours; low (100°F) stretches to 8+ hours, matching independent tester results, not inflated marketing claims.
Q2 Can I set different temperatures for my left and right foot?
Absolutely. The app lets you customize each foot independently in real time, so if one side runs colder, you can dial it up without overheating the other. It's true dual-zone control.
Q3 Are they safe? I saw stories about fires
No. ThermoStride uses certified Li-ion cells with overheat protection, the exact safeguard missing from the cheap Amazon brands hit with CPSC fire and burn recalls.
Q4 How do I trim them to fit my shoes?
Compare your old insole to our sizing chart, then trim along the marked guides with scissors, staying clear of the heating panel itself. Takes about two minutes for a snug fit.
Q5 What are the three heat levels?
Low runs 100°F for all-day wear, medium hits 122°F for real cold, and high reaches 140°F for the deep freeze. Cycle between them with the onboard button or the app.
Q6 Do I need the app to operate them?
Not at all. There's a physical button built in that cycles through all three temperatures. The app just unlocks extras like timers, real-time monitoring, and independent foot control.
Q7 Are heated insoles better than heated socks for ski boots?
Insoles win for ski boots: socks add bulk and shift batteries awkwardly in an already-tight boot, while insoles target the toes directly. Stick to trusted brands, off-brand socks and insoles alike are hit or miss.
Q8 Do the batteries come with the insoles, and are they replaceable?
Yes, each pair ships with its rechargeable Li-ion battery pack included. It clips on and off easily for charging or swapping, so you're never stuck waiting on one shared charger.
