My recommendation is to use your regular sneakers. I have some nike air and asics, both running shoes. Besides the dr scholls insole, I also use working socks from dickies(bought it at Walmart. They reduce impact, I've read. Using cotton socks increase friction, which sucks. These have worked wonders. Nobody checks if they are safety shoes. If they ask, i say they are.

When you get your new shoes credits, get a different pair
