These are the best shoes I've ever worn to work. They support the arch of my legs so they don't put any strain on my back. I have to say that running a marathon is not the best way, they didn't reduce the stress on my joints especially my knees and hips. I have run two marathons in the Saucony and this was my third, the shoes are great but I have never felt any joint pain with the previous Saucony. Overall they are great for the job.
