I had bought a 10 pack, took 2 out of the pack warmed it up with my hands. Then put it in my boot. At the tip where my feet are. It stays warm cause anything touching them activates it and keeps it warm. Pause
My feet starting getting a Lil cold until I did that but that warmed them right up. I did it right after halftime and was good. I had the hand warmers for my hands all game held them with my gloves.
You can hold the warmer with your bare hand and be straight. I took my glove off to get my ticket and vaccine card to show at the gate, felt like my hand was gonna freeze off. And that was just not even 5 mins. Started using the warmer in the stadium and was good
