Rated 4 out of 5 by Does stop cold toes Have had problems with cold toes in my ski boots for years. Sometimes means I have to go into a cafe and take boots off to ease the discomfort. These electric foot warmers have solved the problem and kept my toes happy for 7/8 hours in my boots. They don't make your toes warm but they do stop the discomfort from being too cold. Lasted all day on setting 2 and were easily fully recharged overnight. I had the batteries on the back of my boot and although it felt a bit strange and I was concerned about knocking them off or being hit by a chairlift I managed without incident. Pulling ski trouser over them obviously helps ensure that stay on and I didn't notice them at all while skiing. 27 April 2014
Rated 4 out of 5 by Good product, needs to be fitted well In the first few days the disc seemed to be too hot and was burning my foot. Having consulted a specialist boot fitter in Courcheval I discovered that Snow and Rock had only done half the fitting! Once they were fixed, the heaters were wonderful and were warm enough on the first setting and the batteries kept going all day. A friend recommended this brand very highly and I'm pleased with them. Have since found out that these are fiddly so suggest you get some expert help. 23 February 2014
Rated 3 out of 5 by Great all the time it was working! Whilst it was working the product was fantastic. I have never had warm feet whilst skiing and this transformed my holiday :-) However, you have to keep checking that it is working which is a pain. I found that the lead to the battery frequently fell out ie if you have a crash, get your leg knocked by the turnstiles or go to the toilet etc. Also, on level 2 my boots would only stay warm for about 5 hours which is not long enough. Level 1 was not warm enough and if you use level 3 or 4 you get much less than 5 hours use. So, whilst a great product, it is not without its faults and I hope that the manufacturers will improve it over time. 04 February 2014
Rated 5 out of 5 by Best skiing accessory purchase by far! This is by far the best skiing accessory ive bought. I used to always suffer with cold feet, toes especially! I got these as a present and ive never looked back. Warms the boots within a minute or so and lasts all day! Brilliant buy and i would 100% recommend this wether u suffer cold toes or just want to take the chill off! 06 January 2014

Rated 5 out of 5 by does what it says Easy enough to set up in your boots and snow and rock offered to fit them if I wanted. On setting 2 the batteries last 8 or 9 hours and keeps your feet just right. you just switch on before you go out and you dont notice any particular heat but your feet dont get cold either. I found out the difference one day when one foot was freezing cold but I realised I had forgotten to turn the battery on. the batteries clip on easily to the top of your ski boots and you forget about them once out skiing. easy to recharge. if you get cold feet, I think these are the best. 18 February 2013
Rated 4 out of 5 by Finally I can feel my feet in my ski boots! My feet are like ice for a good majority of the year...So in ski boots a good part of my foot pretty much feels like its dying (Even in custom made, top of the range ski boots...which I have...) I was sceptical about whether these would work, but I'm willing to try anything to stop my feet from falling off during the season! Took the Snow and Rock team about an hour to install them into my boots and a 1min demo to show me how to use them (FYI you need to own your own pair of ski boots to use these) 4 different light settings to crank up the heat, I tried these out in Switzerland and pretty much always had it on number 3 (4 being the hottest) my foot didn't feel overheated or like it had blasting heat directly onto my soles, my foot just felt normal and not numb, exactly what I wanted... Switzerland had fairly mild weather in December, I'm off to Val Thorens in France this week in January, known for being incredibly cold...lets see how the Hotronics fair in some tougher conditions! Fingers crossed ill come back a happy camper with all 10 toes... 08 January 2013
