MR.ICE Toe Warmers and Insole Feet Warmers and Body Warmers - Disposable with Adhesive Back Warmers - Air Activated Heating Patch - Long Last to 8 Hours Hot Warmers

I am marine biologist in Alaska and use these often for long, cold days in the field. They last for hours and are easy to apply. They stick well to my sock all day long, and keep my toes warm.

Afortunadamentre los puedo encontrar a traves de Amazom

I like that it will warm your feet and that it comes in pairs and it has adhesive to keep it in place, no matter what you buy in life, it can always be of less value. The insole warmer is very hot under the feet, even after you put socks between your feet and your shoes. I'm going to try thicker socks to see if that will help, also the pad is thick under you feet, less chemicals per pad will help a lot, when it comes to your feet you want the best comfort. I have to move the pad around in my shoe to find a comfortable spot otherwise I feel like I have a rock in my shoe. I'm not giving up because it do work., yes I will buy them again.

Engaño total en la foto del producto.El producto llegó en una bolsa con cierre (no en caja como se exhibe en la foto), sin mayores medidas de higiene y presentación.Adentro, de manera muy rudimentaria, envueltos en plástico casero, 2 paquetes de 10 piezas.¿Qué necesidad hay de engañar al cliente?

I wear these for the winter and they were extra hot. They do not look like the picture on the cover, which was good.
