Boots are fine but they should be lace up. I was using a cutting torch under a piece of farm machinery and had on engineers boots. When I crawled out from underneath I didn't realize that my pant leg had pulled up and slid inside my boot instead of over it. I went back to cutting from a standing position and dropped about a .25 caliber goober in my boot. By the time I shut down the torch and pried my boot off it had burned about halfway into the top of my foot. Didn't hurt all that bad, looked like a brand after I pulled the goober out with a needle nose plier. Healed rather quickly but I still have the scar today. RD
