Warm Feet Are Happy Feet

Whether you’re up in the deer stand or on the shop floor, when your feet get cold, life is no longer fun. You can dress as warm as you want, but sometimes it’s not enough — that’s when it’s time to slip some Cozy Feet foot warmers into your shoes. Powered by a few AA batteries, they’ll warm your toes in seconds.
The low-voltage insert is shockproof and reaches a safe maximum temperature of 98°F. The one-size-fits-all insert measures 4-1/2″ long by 2-7/8″ wide by 6 mils thick.
A set of inserts runs $25.

Yeah, and Tim probably used a “little more” power!
