Nathan ryan: I usually wear something other than socks when I'm using a grinder, but I have found that it's lot's of fun to cut aluminum or copper or other metals that don't spark completely naked with no guard, but the shoes are a must!

Emanuel mifsut: Why do all the work on the ground? If he had a pedestal drill the job would be much easier. You will learn to wear safety shoes when you drop a hammer on your foot. Angle grinders should be used with all safety equipment ,gauntlets, long sleeve shirt and safety glasses
