Can't say enough about this product. I have been wearing thee for the past 4 years. I don't spend one day between November and March without these in my boots. I put them on in the morning and they last all day. I am in my late 50's and I work outside; by wearing these my circulation stays good and my toes don't get cold. My son lives in China and he wears them with the same results, and it gets a lot colder where he lives. GREAT PRODUCT!
We use these for skiing and they are great! Just make sure to put the shiny side down. Also as you are putting them in your boots - don't wait too long between opening the package and putting them in because they can poof up (but that goes away after you put your foot on them and put weight on them). The M/L fits my shoes (women 9) and my husbands (men 9) great.
I love to snowboard, but my feet start to hurt about 10 minutes in due to the cold. I've been snowboarding for 8 years, and for the first time, my feet don't hurt if I put these warmers in my boots! They work instantaneously and last for my full day on the mountain! WOULD HIGHLY RECOMMEND!
My husband is a hunter and when you hunt in ND at this time of the year, your feet get cold when you are out for extended periods of time. He has enjoyed the warmth of these inserts and will be happy to have them when he is our snow-blowing too!
