Does anyone have practical experience with the Thermacell Heated Insoles product?
I see they have a wireless Bluetooth rechargeable model and wonder if they are worth the time and money.
Application would be winter fishing Pyramid and steelhead.
I tried some battery heated socks back in the 1990s that were wired and used a few D batteries and the performance was dismal.
Any insights related to fit and sizing would also be appreciated.
