Don't misunderstand me but I really learned a lot about simple shop floor... my basement shop has a concrete floor, only covered with an acrylic paint I had to renew a couple of times in the last 27 years. No humidity issue. No foot fatigue... I always use a a pair of comfortable shoes, never barefoot there. Floor temperature range in the year from 18 to 22 degrees Celsius. I cannot see a reason for me to change that.

It is a surprise for me how complicated an apparently simple issue can be. It is instructive SMC forums... and a little bit funny.
