The “Grizu” from Scarpa are heated show insoles that bring the temperature inside your boot up to 38° Celsius—warm enough to be comfortable, but in theory not so warm your feet will sweat. The insoles can even be submerged in water and will automatically shut off, able to be operated again once dry. They can heat your shoes for about seven hours before needing to be recharged.
The system should be available this winter for a hefty $250.

These were released by Sidi for cyclists last winter. Based on the look of the case, charger, and remote, they look like re-branded versions of the Sidi heated insoles.
Reaction to the Sidis have been mixed among our customers. Reliability is somewhat poor so far, with some outright failures as well. Also, oddly, the wireles remote seems to conflict with some cellphones.
38°C is comfortable?
