Great shoe!
Size: 12, Color: (001) Black/Jet Gray/White
True to size, nice style, lightweight, and extremely comfortable. Purchased them before a trip that we did a lot of walking and never had sore feet. Did not need to break-in.

Perfect fit with or without shoe orthotic
Size: 7.5, Color: (101) White/White/Metallic Silver
Unbelievably comfortable. I have a lot of problems with my feet, but with these sneakers I can fit my shoe orthotic inside and still have a comfortable feel. I have ordered these shoes over and over. Highly recommend.
