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.

I use 2 pairs of socks

The toe water pad does stick where I need it on top of the arthritic toe but it just wasn’t warm enough on cold winter day….it is also thick enough if you have to wear it on top to be selective on what type of shoe you can fit into…a flexible rounded toe shoe is best.

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.

It’s perfect for freezing cold weather

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.

Good for older people who have issues of cold feet
