I have gouty arthritis and when my feet swell I need shoes that can flex. The laces can be easily loosened up to the tip of the foot. Mesh sides offer flexibility for a comfortable fit. In combination with some gel inserts, they are worth their weight in gold. They can be comfortable on the REALLY bad gout days, but usually wear for a few hours to make ends meet. The fact that they are all black and have a clean look allows them to go with most business casual outfits.
