Mizuno upgraded its Men's Wave Rider 17 Runner Shoe and made it lighter and more efficient. Dynamotion fit makes this neutral trainer move in harmony with your foot without ever pulling or sliding against it. Mizuno made this possible by covering the upper with AirMesh, which is a stretchier form of mesh that blends the maximum amount of breathability with long-lasting durability to keep you running in this pair of shoes for a long time. Mizuno also used less synthetic overlays than the previous models in order to shed as many ounces off as possible without hindering the durable construction of the shoe. The U4ic midsole is 30% lighter this year, and it provides more cushioning and the same dynamic, fast feel that made all the previous Wave Riders best sellers. SR touch is a new cushioning material that absorbs shock and keeps your heel-to-toe transition smooth and fast with its quick rebound properties. SmoothRide grooves within the midsole make for smooth, rocking transitions, and the X10 sole uses an incredibly durable carbon rubber that allows longer wear in high impact areas like the heel strike.
