After I Buy Ammex HW4 Heatworks Air-Activated Emergency Adhesive Toe Warmers (Box of 48)The Ammex HW4 Heatworks Toe Warmers work great for very low temps. I have these and the Ammex Hand, pocket and glove warmers and they are the best warmers that I have been able to find. The hand warmers last longer at 7-8 hours but these foot warmers fit your boot / shoe really well and last about 5 hours. I used these last week when the deep freeze came to the midwest and we had wind chills of -45, they worked just as expected and kept my feet nice and toasty.
They are activated by just exposing them to air and shaking it for a few seconds. No braking or shaking for 1 minute like others. Its error proof and user friendly.
Overall these Toe warmers are the perfect thing to use when needing extra warmth on your feet. You can also use them as hand and pocket warmers as well if you want to so thats nice. I would recommend these to anyone looking for great warmers that last long and work great.
