  1. Thank you so much for all the information regarding industrial boots and how to find ones that meet safety standards. My wife and I had no idea about all of the triangles that designate that they are safe. I do not think a lot of people know about this and go out and simply buy boots that are visually attractive; however, may not be the best boots to work in. Thanks for the advice!
