Woah, that's a long name - but some darn awesome kicks! Let's break it down. The ultra part just means that this model uses some of Nike's most lightweight and mobile materials. The shoe literally feels like air! It's an Air Max so you know it's got that air sole unit going. The entire upper of the shoe is a knitted sock-like structure, so that's where flyknit comes in. This ain't one of grandma's sweater's!
