I work at Home Depot and on my feet for over 10 hours a day. I am on concrete as well. I love these shoes. I also purchased another pair model XA Pro 3D Ultra 2 GTX Running Shoes. I have three pairs of Salomons so that I can rotate them everyday. I have plantar fasciitis and man these shoes help so much. If your feet get sore and tired or you have plantar fasciitis I highly recommend these shoes and brand
