Question: I bought  a pair of these and attached them to my ski boots, 3 days later one fell off, where can I get a replacement battery pack?
Document: I have had Hotronics for at least 15 years. My old set finally gave up. I bought a whole new set and my first day out attached the batteries to my boot strap. After 4 runs I went in and realized I had lost a battery pack. We looked and looked but could not find it. Looking for white on white makes it very difficult. So I bought a new one. I now have it connected to a strap that goes around my leg.
I could've glued the black plastic piece to the white bottom but didn't think that was a good idea for repairs down the road.When I got home, my local ski retailer sent them back to the company & they gave me a new battery pack at no charge, which was great! Fantastic customer service!!! I still had to ski with one cold foot the rest of the week however. I give it a 3 because the other battery pack worked great and kept a charge all day.
This is the second pair of Hotronics I have had in my ski boots and they are great. I always had cold feet until skiing in Vermont about 10 years ago when I bought a pair in the ski shop. I would not be without them!
I tried everything. Lots of socks, fewer socks more air between, shoe covers. I seem to have crappy circulation since my toes and fingers get cold. The feet were easy to take care of. I bought an older version of these and they lasted seven years before one battery finally stopped taking a charge. That's pretty good. So I bought a new set this year and they work just as well.
This fall we had some cold weather so I took the Hotronics out of my ski boots and installed them in my hunting boots. These were purchased as a replacement for my ski boots. The heaters mean being able to stay out all day without the pain of frozen feet. Like they say &#34;If you don't think they're doing anything, turn one of them off for a while&#34;. You'll feel the difference.
my snowboard pants have gaiters, so even if the battery pack fell off a boot, I don't think it would go anywhere.overall, would recommend if you have cold feet.
absolutely worth the money. I have custom made insoles from Intuition (custom made at BootLab in Vail) and ski about 30 days a season. I was still getting cold toes. Typically cold toes are caused by poor circulation or having a boot that's the wrong size.My boots are custom, and absolutely the right size, i just get cold feet. period. With this product, it's gone.Here's the thing.
I have used Hotronic heaters in my ski boots for 10 years. I bought the E4&#8217;s to replace my 10 year old batteries which no longer hold a charge. The E4 batteries are slightly larger overall than the old batteries but they are thinner and lighter and more powerful. The E4 batteries charge in 3 hours or less compared to the old batteries which took 12 hours to charge. I could not ski without Hotronic.
I have a custom foot bed that I have mine attached to so I didn't use what they sent in the kit. I would advise making sure you attach the battery pack well to a strap or you may encounter my experience. I have tried the toe warmers that you stick on the bottom of your foot but they are uncomfortable and don't last very long. You can not feel the small heaters inside your boot. There is no bump to bother you.
Toasty feet, what could be better on a freezing Vermont ski day! The installation instructions could have been clearer but that's the advantage to having a son that is in the ski bis. So if you're going to install yourself just get good advice.One nice feature is that the boots that they were installed in are Fisher that has accomadations for the wire feed and a handy slot to hang the heater.
