THE HEAT COMPANYToewarmers - 5, 15 or 40 Pairs - EXTRA WARM - Adhesive - Foot Warmers - 8 Hours Warm Feet - Instant Heat - Air Activated - Purely Natural

I have to call this product a bit of sorcery because it works so well! I took it with me on my holiday in January in Norway (above the Arctic Circle) where temperatures reached -15C, and it truly amazed me. The first few minutes of use were almost too hot, but it would cool down over time and was perfect to use. It provided an instant warmth that helped keep me comfortable even in freezing temperatures. Not sure about its sustainability as it's a single-use product which I typically avoid, but it's not something I'd use every day.

Works well for Raynauds. Don’t necessarily make your feet warm but it stops your toes from going numb in the cold! My boyfriend also uses them in the colder months for works and likes them

I have poor circulation and in winter, cold feet, these help. I put them on over sock and if they might get too warm I put a pad free sock on first and then the sock with pad on top. It works for me and relieves uncomfortably cold toes. Two sock system can avoid chilblains by not overheating toes.

These foot warmers are great. I suffer with cold toes and in winter, and hence in the wet and snowy weather it is a real problem. These solve that completely. A few points I have learned in using them: 1) they heat up when exposed to the air. The longer you leave them in the air before putting your foot in your shoe the warmer they get. If you do not allow enough time they do not get warm enough. If you wait too long they get very warm. If you wear them for a while then take your shoes off, remember they will get hotter if exposed to the air again. Be careful to remove them when you no longer need them. They do not get stuck to my sock - they are just right and comfortably thin.

Lovely to yse until they ware out

Item great as described. Will be taking to Lapland in March. Can’t comment on effectiveness yet. Amazon however poor delivery as usual. Cannot read instructions in door to leave in safe place. Left hanging out of letterbox on a busy road. Last time left on doorstep. It’s a wonder my packages haven’t been stolen. For this reason no longer using Amazon. How hard is it to follow a simple instruction. Worst delivery ever.

My toes get very cold during the winter months and often get chill blains. I have used these daily for the past two weeks. After an initial 4/5 mins you can begin to feel the heat, this then remains constant until it starts dying out near the end. Haven't had any chill blains yet, will continue to purchase.

Worse than useless simply do not heat as they should
