I bought some Keen low top shoes as I all the redwing shoe stores didn't have any model 6640 in stock. They have a higher arch which is nice and a so many day comfort warranty. I couldn't go another 12 hr shift without something different as I was shuffling my feet at the end of my shift two days ago, because I couldn't lift them. I guess I have a flat foot as well. I tried 5 pairs at the shoe store. The reeboks were nice and cushy but something was sticking out in the little toe side that was a defect so the guy couldn't sell them to me. My feet were a little better with these shoes as I could walk a little bit better at the end of my shift but I was still sore as hell. I don't know if these need to break in or if my feet are that overly sensitive. Or that I need a different shoe again, maybe double up socks?
These are the Keen shoes. Detroit Low ESD is the model w/ a 90 day comfort warranty. http://www.keenfootwear.com/us/en/pr...d/dark%20brown
