Free delivery and returns on all eligible orders. Review: Amazing!! - The best! Used in Finland at -25 and they were a life saver they made the cold bearable! Review: Great with one adjustment - Like a lot of people, I suffer terribly with cold hands and cold feet. As my husband and I are keen walkers, this can be a real issue in the winter as the pain in walking boots can be quite severe. First thing to note is that each pair is individually wrapped. As I suffer much worse on one foot I decided to try only one foot heater and save the second one in the packet for the next day. Unfortunately the heat within them is activated as soon as you open the packet so both need to be used at once and you cannot save the second one. The second thing to note is that they are like big plasters that you remove the backing and stick to your socks. They are supposed to be positioned under the toes within your boots/shoes. However, after a couple of hours of heat, the chemical inside tends to harden and I found them slightly uncomfortable under my toes after a good (5+ hour) walk. For this reason I decided the next time to try putting them on top of my toes. I found this to be much more beneficial for both heating the toes and for comfort factor - now I don’t feel them, I just feel the warmth. Heat wise - they will never get as hot as a rechargeable hand warmer but they are hot/warm enough for a good 8 hours (the max I have tested them). Very portable, convenient and easy to use. I keep a pouch in my car and a set in my walking boots so I’ve always got one when I need them. They can easily be used in gloves as a hand warmer but the ones specifically for hands are usually a cheaper option. I bought these on offer and they have helped to eliminate painful walks. Very happy with the purchase and worth the 5 stars I’ve awarded. ## Features - FAST, LONG-LASTING HEAT - HotHands Foot warmers warm up quickly and provide soothing warmth for up to 8 hours. - READY TO USE - HotHands warmers are air activated.

The Hothands Foot warmers should not be used on bare skin or over thin materials such as nylon. The warmers should be used over a pair of socks. **Q: I have 4 unopened packs and 1 opened. They do not work, why cant i return?** A: Not sure why they don't work, I've had many and not encountered this problem. **Q: How are these disposed of? Can they be recycled?** A: Thank you for your enquiry. The Hothands items should be disposed of with regular household waste. They are not suitable for recycling. **Q: How do these work? 'Core heat technology' as they say in the description is gibberish. re they reuseable? How long do they last for?** A: These products are single-use only (disposable warmers) and should never be reheated. They last up to 8 hours and keep your feet cosy and warm. The technology mechanism behind this magic is purely based on air activation. The ingredients are iron, activated carbon and water come into contact with the oxygen in the air, oxidise and produce heat. This is why you should only remove the warmers from their sachets once you are ready to use them. Hope this answered all your questions. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing!! *by T***Z on 1 August 2026* The best!
