This is a great pair of shoes, I'm a fitter at a distribution center and spend my whole day walking around the entire indoor work area, mostly 10 hours a day but 12 hours when needed. I can tell you, to get through a week you need the right pair of shoes. They are great because of the gel soles, they cushion your feet but still offer great grip. They let me walk all week and I only got a little nauseous towards the end.
