Sometimes the simplest answer is right in front of my face and I dont see it. There is a Red Wing shoes store near my house. Which model do you have?I don't like using mats. Pain to clean. If you get shoes made for working on concrete you don't need the mats. I have a pair of Red Wings boots with the soft rubber diamond pattern sole. It's like having the mat attached to your feet. I can work in the shop for 12+ hours and my feet don't hurt, 4 hours or so in tennis shoes and my feet are screaming at me.
