text: I'm on foot at my job for 9 hour shifts with a break at the 5th. After a couple of months with my Nikes my knee joints and foot over all would feel sore at the end of the day. At first these shoes where awful cause when walking, because the part that creases would dig in to my foot... I guess its part of breaking them in. After a week however the shoes are amazing. They took all joint and foot pain/ache. They definitely make my job easier.
