Warm footsies for sure
This mat works great. I use in my unheated shop (and it's been a cold winter) while I do tasks that require me to stand in one place. In a cold shop, this makes your feet get cold quickly. The mat is laying on bare concrete floor and in spite of the cold concrete underneath, it heats up in a reasonable amount of time and maintains its temperature well and keeps my feet warm without movement. It seems to be well-made and pretty rugged. Recommended highly.
