I'm having issues with arthritis in my toe joints, seems to get exasperated on the days I spend hours in the shop. Would like to try a few mats, 3 around the workbench and 1 in front of the TS. I do wear good shoes that were recommended by my podiatrist, so the mats will supplement those. Does anyone have experience with a brand of mat that they can recommend? I have done a fair amount of reading on mats, but the selection out there is kind of mind boggling. Floor is concrete.
