Good size
How it looks on the model is how it looks in person. The material is lightweight and quality. Enough room for phone and wallet and keys. Adjustable strap works with ease. Under Armour is my favorite athletic brand. They do not disappoint. Love this bag.

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.
