HEAT EXTREME Air Activated Toe Warmers, 10 pairs - Lasts for 14 hours!

Don't work well for skiing as there's no airflow (oxygen required for Exothermic reaction) in boots.

Wish I had paid attention to the previous reviews. The toe warmers barely warm up, even inside the warmth is barely noticeable. Three people in my group used these for one sports event and they didn't work for any of us. I tried again, used a fourth pair and still NO HEAT. It is about 30 degrees in Michigan and I really wanted warm toes while I watch the kids play their spring sports. SO DISAPPOINTED.

Easy to use in cold weather. Warmers are a good size and keep warm for several hours. Whether I am watching my kids play sports or shoveling snow, these warmers are necessary to keep my feet from freezing.

Great price & quick shipping, but the toe warmers did not perform as expected. 2 of the 10 pairs that I purchased did not even get slightly warm. The other 8 pairs kept my feet fairly warm, but the heat only lasted about 6 hours.

I've used several brands of toe warmers on steelhead fishing trips in Oregon in November thru May and the 5-6 hour warmers just don't last long enough. The 8-12 hr warmers are a bit harder to find unless you buy 36ea in bulk which isn't a good idea considering they may not have a long enough shelf life. This order for ten pairs meets my needs for one season. As for the warmth factor these are great and not too bulky with thick socks plus the adhesive back helps keep them in place while slipping into waders and wading boots.

These do not even work! Maybe I got a defective pack? Not worth sending back!!! I've tried 3 pairs, no heat whatsoever!!! I've had these in the past and they should get hot and warm ties for hours on end!!! I got duds!!!! Not happy!!! :( I have severe Raynauds and really needed these.

A must have for cold winter days spent outside. I live in rural Alaska, and these are a great thing to have on days that are spent outside in negative temperatures. They are easy to put on and stay put in my boots. I always carry a pack in my bag, just in case I get stuck somewhere cold. A great price for the quantity and quality!

I applied them as directed to the outside of my socks before going to sleep and they heated up fine; by 3am, they were warm, and at 6am, they were cold. Since I was in the desert, and not wearing boots, the environment was less moist than they were designed for, so it might be user error. Also, being not in a boot, they eventually peeled off my socks. Looks like I might have to wear double socks to keep them in place and raise the humidity.
