I work and ride at a barn, so I use these during the cold winter months. They really do keep my toes warm up to 5 hours. I highly recommend Toasti Toes! 5 stars

These are fantastic little warmers that work fast and really do last up to 5 hours. It is a simple chemical reaction (charcoal, iron powder, vermiculate) inside the packet that reacts with oxygen (air). It is very useful for immediate warm-ups when out in the cold. They are also very useful for after skiing or skating in the boots, but be warned that warming your feet can cause sweating which will make you even colder. Use them only after you are done in the snow. 5 stars

I could not have survived this frigid winter without Toasti Toes. I'm wearing a pair right now. I like to walk, and I was able to walk every day thanks to Toasti Toes. They last all day -- I usually open a new pair about 6 am, and they're still warm when I crawl into bed at night. I will keep using them, at least until I can afford to retire to the tropics! 5 stars

These toe warmers are great to put in your biking shoes when the temperature drops below 40 degrees. The adhesive patch sticks well to socks and the heat lasts for many hours. I would have given them a 5 if they got another 5-10 degrees hotter. 4 stars

This is a fantastic product for anyone who has cold toes/feet and can't find any other way to warm them. I have tried battery heated socks and they just don't compare to the warmth of these toastie toes. Also, the adhesive pad sticks to your socks and there is no slippage in your shoes. I would definitely recommend these. The only downside is that they are not reusable. 4 stars
