WORLD-BIOToe Warmers Adhesive 10/20/30/40 Pairs - Long Lasting Safe Natural Odorless Air Activated Warmers Up to 8 Hours of Heat - Heated Insoles Toe Foot Warmers Keep Foot Warm in Chill Winter

These are great at warming up my to s as needed.

Used while deer hunting in November. Held up pretty well.

Dont shake these. Strangely the heat up when exposed to air. I wish you could shake them to make them hotter. They are warm and do the job.. just wish they were hotter.

These are actually much longer lasting than the Hot Hands toe warmers. These are still slightly warm even at 12 hours after opening. Definitely a 5 star product. Sticks well to wool socks.

I'm a nearly everyday skier at Big Sky, Montana and have been using World-Bio toe warmers for years (I actually use them in my gloves as the adhesive sticks to the top of the glove keeping them in place perfectly).I recently reordered a package through Amazon and unfortunately this particular batch simply does not warm up. It my be that this is a one off and I received a lemon batch. It's a new to me design and they say they should stay warm for 7 hours as opposed to the type I am usually sent that say they should last 8 hours. This batch was manufactured in Aug 2024, so they are new. I have tried at least a dozen of the ones I recently received and they are flat out not working.As I say, this is not a case of user error, in that I have been using their product for years without complaint.My suggestion is give the 7 hour models a pass and make sure you get the 8 hour models. Seems like there wouldn't be much difference, but the packaging is different, the adhesive is a bit different and the feel of each toe warmer is different.I'm all for change but not so much if the product does not work.

I’m a crossing guard in the Northern Illinois region. Standing on the corner without these toasty warmers in my boots would be a sin. I use a pair everyday on our most frigid winters days and my feet never get cold. I keep a set available in my glove compartment as well. Excellent investment for those who work outside exposed to the cold elements.

I bought the bag with 40 pairs. I used them in my shoes and also as my hand warmers. Some pads worked and some pads didn't. For the pads that worked, they work well up to 7 hours. I find the warmness level are inconsistent with each pad. Sometimes it become really warm and some just merely.Some of the pads' filling has harden before first use. So there was no way I could shake it to make it warmer.I find them better as hand warmers than toe warmers as there are not much air in my boots to reactivate it once it is no longer warm. I had a few times to take them out from my boots to shake them to get them warm up and then put it back in my boots.

I use 2 pairs of socks
