Best foot warmers. Fit in shoes without bulk and warmth last all day.

I gave this 5 starts because it works really good for what I need it for. It doesn’t stay hot for hours. I used 2 packs in one day. In the morning and at night.

These kept my feet toasty warm. I was really enjoying the warmth. Then I had to walk about a quarter mile to Highmark Stadium in 28° weather. They got so hot that I had to take off my boots and pull them out to keep them from burning my feet. I recommend you take these with you where you’re going and put them inside your boots, once you’re sitting down to ice fish or watch an outdoor game. After they got so hot and I took them out, they never kept my feet warm again when I put them back inside. These are activated by friction, so keep the friction to a minimum until you’re ready to sit down and enjoy them. I’d give them five stars for being overachievers, but I gave them four because the manufacturer says nothing about walking being a problem

Best product ever for my use! I have spent so much money of different types of socks thinking they would resolve my feet freezing over while playing soccer in sub zero temperature. These are things did the job. They stayed in place, are thin enough to not cause fitting issue and kept my feet warm thru my activity about 3-4 hours

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

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.

Love these. I walk outside in the winter and these keep my feet warm the entire way.

These are much better than the Hot Hands foot warmers. They stay warm all day.

Took these to northern Norway in January and were effective. you can wrap up as warm as you like but if your feet or hands are cold it is not enjoyable. With these I opened them up, gave them a shake (probably completely unnecessary) then put in my shoes ten mins before putting them on. Kept feet warm without getting hot and lasted for hours. Pity they are throw away after one use but that's just how they work

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.
