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.

My Husband uses these for hunting. He says that they keep his feet warm while sitting for a long period of time, They are not hot, just right . But the sizing could be better as he has to push them to the front for his toes, but it does not bother him or feel funny in his boots when walking.
