They are not bad. I've had them for a couple years and use them mainly icefishing and late season bow hunting. They work as intended but
are fairly stiff. I had to get used to them maybe an hour before they felt comfortable in my boots. I wouldn't put them in and walk 10 miles though
I received a pair 2 years ago and use them late season in the tree stand and ice fishing, I myself love them, always had trouble keeping my feet toasty sitting still for long periods and they work good. Not a bad price, they usually are a Black Friday deal in lots of locations.
I personally didn't have good luck with them. Took them back to scheels and got money back. Would rather buy the hot hands style you slide over you insole which expire 6-8 hrs later.
bought a pair 2 years ago and haven't used them a whole lot. They arent the most comfortable insoles. I mainly use them for late season goose hunting. they did help a lil bit but didnt seem to last very long.
I have a pair that worked well for ice fishing, but I thought I'd use them in my waders, and they're not very comfortable. My wader boots are less support than my regular winter boots I guess.
They're good, but not something I guess I'd have to buy again.
Kinda trick to have a remote for your feet though...
