I travel a lot of ground at my job,hard concrete floors and have knee and feet issues also. Have bought many shoes that just don't cut it and haven't purchased a "athletic" shoe for many years because they just weren't providing the cushion and support I needed, usually purchased Nikes and hadn't tried the Saucony brand. Holy cow what a difference! These shoes are like butter. Fit is absolutely perfect and true to size, massive cushion and support. My feet and knees feel like new. Saucony you have a loyal new customer and I am going to buy another pair.
