TerraTherm Insole Foot Warmers - Air Activated - 8 hours of warm feet - 5, 10 or 30 Pairs Heated Insoles - 100% natural warmth

These are brilliant thermal pads, they keep my feet warm when cycling early in the morning (~6am). They're super eay to use, and very comfortable. The heat in the pad is oxygen activated, so I open the pack about 5mins before I'm due to leave the house, and waft them about to get some airflow over them, then I'll leave them for 2-3mins, before inserting into my shoes and leaving. Yes, they add a little thinkness to the inside of your footwear, so allow for that. I use them with size 43 shoes. Things to note: [1] They are oxygen activated, so if there's no airflow in your footwear you might have to re-activate them every now and again, yes by taking your foot out of the shoe. [2] These can get properly warm, if your foot moves a lot of air inside your footwear (like if you're jogging on the spot), so make sure to wear suitable socks. [3] One side of the insert is shiny, the other matt. Put the shiny side face down into your footwear. [4] In order to seal the active material into the insert there's an approx 10mm band around the edge of the insole where there's no activate/heating material. [5] They're single use. [6] You'll know when they're spent because the active material gets firm in the insole. [7] When they get wet...like raining on them wet because they deactivate.

Excellent, does the job feet lovely and toasty

No hype,these foot warmers kept my tootsies toasty on a damp chilly night inside my lightweight but substantial warmth hammock tent sleep system.My sleeping bag foot-box always keep my feet warm even on Winter nights, but these were a cheap, minimum-space saving addition for an even better night sleep (8 hours undisturbed).

Bought these as i suffer with cold feet, especially when im outdoors i cant feel my feet. So I used these and they get instant hot which is nice, but can be uncomfortable but I didnt mind them being hot. Will advise putting few socks on just so you cant feel the instant heat, but they work and im very happy and will buy more again. They stayed warm for a very long time didnt have to worry all day, thank you.

I ordered these as I work outside. These are brilliant, and exactly what I needed. Warm feet all day, so I can highly recommend them! Will definitely be ordering more! Just check sizes before ordering.

Way too small and also they slide inside the shoe making it feel uncomfortable

These are hot to the point of very hot, and last ages, for the money I can't see how it gets any better.

First class product Cold feet no more! Simple to use for “toastie feet”

Bra pris, rätt vara och snabb leverans

Super bien, el pie caliente durante horas, no molesta.como otras que se nota arenilla, en invierno llevo siempre en bolso

These are great. They slip into your shoe and keep your feet warm for at least 8 hrs even when I'm snowshoeing.

Heel goed

Ok
