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!

Great shoe, comfort
Size: 11.5, Color: British Tan/Ivry
Love these shoes, they're super comfy. Laces stayed tied all day. I wear them in a business casual environment, or if I'm going out for a nice meal with my wife. They look good, the color is unassuming and neutral. they also elevate my height, I feel like it gives me an inch or so more versus regular shoes. This is my second pair!
