Review on 🔥 Grabber Toe Warmers - Extended Duration Natural Air Activated Warmers - Up to 6 Hours of Safe, Odorless Heat - 40 Pairs by Trae Joubert

I bought a pack of 40 at the end of November 2019; Packages have an expiration date of 09/2022. So this box of heating pads is good, fresh, sold and delivered by Revain. Fair warning that I use them in a way that half violates the warning on the packaging, but I take precautions to avoid burning. Specifically, I wear a lightweight wool sock against my skin and then a waterproof ShowersPass wool sock over that. ShowersPass socks have 3 layers and are quite thick. So I bought shoes half a size bigger. I put the heating pads over my socks at an angle over my toes so that the rounded tip points to the outside of the big toe and one of the straight edges goes over the tips of the other toes. That way all my toes are covered. I also only use them when the outside temperature is 45F or colder. I wear them for running outside in the winter. I have Raynaud's disease and in the past I've had trouble walking in the winter because my toes get numb when the veins close. However, since using these heating pads my toes are fine even when walking on ice and snow. (Kahtoola NanoSpikes are a winter runner's best friend!) I don't run outside for more than 6 hours (usually around 1.5 hours) but I checked them out a few hours after I got back and they were still quite warm. (I won't throw them in the trash until they're cool.) Wearing them over socks helps keep my shoes in place while I run. I tried wearing them under my socks but being a sprinter the padding inside the warmer came off my toes while running so my toes were still cold. Moving the heating pads over my socks was the perfect working solution as I wear very thick socks. They stick to my socks very well, but they're not too difficult to remove when I'm ready. Highly recommended!
