Is anyone using Hotronics or ThermIC's for winter riding? Any preferences?

For those who don't know what they are, they're heated insoles that go in your shoes and attach to a small battery pack which straps to your leg.

I figure they may be a good investment since I can also use them for skiing or hiking.

I've use Hotronics a few times in cold weather

Works great but must make sure the batteries are secure.

Bob Shay is the final word on the subject. You can read his accounts on a link on the Hotronics website.

you would be below 25 degrees

And you don't need booties which trap moisture, which reduces the insulation factor.

Skiing, mostly.

"Been using them since before they were called ""Hotronics,"" couldn't ski without them.

For cycling, they work damn well but it's tough to secure them so they don't bounce up and down every pedal stroke. Again, go to Bob Shay's review on the Hotronics website."

They do really work. I am not an employee or paid endorser. Just an avid cyclist.

If you ride in the winter infrequently, chemical toe warmers will cost you less dollars out of pocket and they work great too.

I think I have the bounce thing dialed in

I have the larger of the 2 battery types of the Hotronics and there is quite a bit of weight to them. Last year I couldn't secure them by just clipping them on to the cuff of my booties. They came loose and almost got caught in the chain. This year I am not using booties, as I have mentioned, they trap moisture. I use straps which were made to hold skis together before ski brakes had that feature. Actually, cross country skis and telemark skis use these straps even today. I clip the battery to the strap which is above my ankle on the side away from the crank. I then loop a rubber band over the top of the battery and secure it to my shoe on the side away from the crank. The batteries stay secure and don't rattle around, even when I am at the high end of my spin on my fixed gear machine.

Wouldn't it work better if...

You extended the wires and carried the batteries in a fanny pack or camel back?

I think there is an option for something like that for fishermen using waders. But my system worked fine.
