I have been having just as good luck with cheapo shoes as with the good ones.I destroy them long before I wear them out.Years ago I bought a nice pair of work boots from Reds Shoe Barn for $159.My first day wearing them I sandblasted a couple of lowbed trailers and some truck suspension.It wasn't until I went to take them off that I saw the steel toes were exposed.The backblast from the blaster had worn the leather right off the new boots.I had used one pallet of sand,(3000 pounds) that had cost me almost exactly what I paid for the boots.Now I put duct tape on my shoes when I blast.The cheap work shoes at Home Depot and Lowes are very comfortable,and seem to last me for months.
