I see them as a mixed blessing. They are certainly more comfortable than concrete, but I roll a lot of things around in my shop, and they are kind of a pain when everything has those small wheeled casters. I have one of the horse stall mats, but most of mine are those 2×2′ squares that interlock. Anyway, it’s a love/hate thing for me. But I admit, my feet are probably happier with them than they would be without them.
