THE HEAT COMPANY Insole Foot Warmers - 6, 12 or 32 Pairs – S, M, L, XL – 9h of Warmth - Air Activated Feet Warmers - Purely Natural - Toe Warmers for Feet - Insole Foot Warmers for Women & Men

These foot warmers were perfect for my trip into the Arctic ! They actually last about 6 hours and keep your feet warm … do let them sit after unwrapping for a few minutes to activate … they are light weight and fit easily into the side pocket if a suitcase

Excellent product if you like a sauna experience in your shoes. I was wearing it for 4 hours and ended up removing the insert. Very hot definitely was made to keep your feet hot…

These will keep your feet warm for a few hours. In my experience they never lasted anywhere near 9 hours. I would say closer to 2-3. They start out very hot and then you kind of forget they’re there. Used them hunting when temperatures were between 0-20 F and they kept me warm. Only “issue” I had with them was sometimes they would bunch up and I would be walking on an uncomfortable lump. Just remember nothing will keep your feet warmer than a well insulated boot and high quality socks meant for the cold.

Anyone who suffers from neuropathy in their feet would welcome the help from these insole foot warmers. They help me a great deal. When my feet are cold, there is nothing that warms them better than these foot warmers.

Comfortable and good heat, but a little pricey for my budget. BUT I still may by more! LOL

I bought these to wear in my boots during a cold football game. However, the warmth did not last as long as package indicated. They were comfortable, but only lasted a couple of hours.

A total must-have for sports moms! They only last a couple hours, but that’s plenty to get through a game without freezing feet!!

I'd recommend this product if you are spending the day in the freezing cold and snow. It's summer in California and my shoes became so hot I couldn't tolerate these hot soles for more than 45 minutes. I get foot cramps and was going to spend 2 hours outside at night. So I thought this might be the answer. I can imagine that in a very cold, snowy environment, they might work very well.

Love these. Very effective, cosy warm without ever being too hot.

Dit had ik eerder moeten weten. Het maakt (bijna) niet uit hoe duur je schoenen of van mijn part snowboots zijn, bij stilstand krijg je vanzelf koude voeten. Met deze warmtezooltjes hou je je voeten echter goed warm. En met goed, bedoel ik dat de onderkant van je achterpootjes bijna in de fik staan. Perfecte oplossing als je lang buiten moet staan of op de motor zit.

Très efficace . Chaleur transmise au dela des 8 heures annoncés

Solette davvero comode e utilissime nei mesi invernali, scaldano molto e per molte ore...ideali per ciaspolate sulla neve dentro agli scarponi.

Los he comprado para días de mucho frío y la verdad es que cumplen muy bien. Tanto los calentadores de manos como los de pies se activan rápido y empiezan a dar calor al poco tiempo. El calor es constante y dura varias horas, suficientes para una jornada larga fuera de casa. Son fáciles de usar, no molestan y vienen bien presentados en sobres individuales. En el caso de los pies, se colocan sin problema dentro del calzado y no resultan incómodos al caminar. Para excursiones, eventos al aire libre o trabajos en exterior, van genial. En general, un producto muy práctico para el invierno y una buena solución cuando el frío aprieta de verdad.
