My old team used foam tiles, and they were very nice and helped with the fatigue that you get from standing on concrete all day (may be a good pitch to the UL safety guys). We would only place them in the center where we walk around the robot cart, where the toolboxes and table were had no foam under them and this worked well. The cart would tend to bunch up the foam if you tried to turn the cart on the foam so the cart was pushed in and out in a straight line.

A word of caution on this foam flooring, it caused a significant increase in the amount of static buildup that we experienced, so do be careful that you do not zap your electronics.
