Quality at affordable prices.
Size: 11.5, Color: British Tan/Ivory
Best old guy shoes. They look great and have support for feet. You don't want cheap department shoes. You will pay for that in your later years.

Look and feel awesome!
Size: 11.5, Color: Optic White/Opti
These are awesome shoes - look great really, really white and clean! Love how comfortable they are - and soooo light. I was a little worried they'd get dirty easily, but I've been able to keep them clean. Fit as expected. If you're looking for a great, comfortable, and affordable shoe, check these out!
