I love these foot warmers. They heat up fast and last for hours.
Great price from Sierra.
Tip: If they are still giving off heat when you are done using them for the day, put them in an airtight container, and they will be good for use on another day.

  • Nice and warm
    Reviewed by Snowman from Detroit on Monday, March 26, 2018
    These are pads that might make fitting into a ski boot a little tight. But they warmed up immediately inside my MTB shoes, though the warmth seemed to disappear after a couple of hours on my bike. So, I wouldn't count on getting a full day of skiing out of them.
  • Warmest, Long Lasting foot care
    Verified Buyer Reviewed by Downriver from Canada on Monday, March 5, 2018
    I order these every year because I work outside during the winter - they last about 6 hours, although they work the best for the first 4 hours. I often take a pair of "Toe Warmers" outside with me, and add them after 3 hours and it helps tremendously.
  • hot stuff
    Verified Buyer Reviewed by Tahoe Gal from Lake Tahoe, CA on Thursday, February 8, 2018
    My husband has poor circulation, his feet are always cold. These foot warmers work well, he does not put them directly on the skin, but inside the shoe that he going to wear with medium weight socks.

    Some rinks are colder than others, and if you're a parent in the stands or helping the kids on the sidelines, I highly recommend this foot warmer. Throw a few in the gear bag just in case you're going to spend a few hours in a freezing stadium.
  • Toasty tootsies
    Verified Buyer Reviewed by Marmat the swamp gardener from NY on Monday, February 5, 2018
    I use these things anytime I’m going to be out in below freezing weather. I like them much better than the toe warmers because they stay in place better. I usually pop them under the insoles as they really get pretty warm sometimes and they harden a bit as the hours go by.

  • “how long does a foot warmers Vance hey can you reuse over and over”
    Asked by hike man from Washington dc on 2/16/2015 3:01:51 PM
    • They last about 4 hours. No, they cannot be used over and over. They are just like the hand warmers only one time use.

    • They last 4-5hrs feeling fairly hot and are warm a couple hours still after that when sitting in a deer stand with 400gr Thinsulate boots on, I have never tried to re-use one, I don't know if that is possible.

    • These are one-use warmers, but they will stay warm for an all day hike.

    • The foot warmers seem to last about 4-5 hours. They are not re-usable. One time use only.

    • This product is recommended to last 4 - 5 hours. Given it's chemical interaction, it is a one time use product.

  • “Do these require that you remove the existing insole or are they thin enough that they don't change the fit of a shoe or ski boot?”
    Asked by jwk from Denver,CO on 1/25/2013 12:00:00 AM
    • They are fairly slim, they are about 2.5mm thick.

    • I wear them under my socks without removing the insoles...they are thin enough not to affect my gait or comfort level.

  • “Can these footbeds be cut down to fit my size? I want to use them in my ski boots. My shoes are usually 6.5 to 7 womens”
    Asked by Anonymous from Unknown on 2/8/2011 12:00:00 AM
    • I don't think so. They are probably filled with an iron oxide powder which will spill out if you cut them down.
      Answered on 3/7/2011 12:00:00 AM by JB from Sierra Foothills
    • These should not be cut as it will render them ineffective.
