The versatile Mizuno Wave Sayonara 4 gets the typical yearly upper update which usually includes a price boost. With typical 10 mm drop and classic construction (in contrast to other performance running shoes like disruptive New Balance Fresh Foam Zante v2), it is a great choice for neutral runners looking to crush personal bests in distances from 10k to marathon.
Major change compared with its predecessor Wave Sayonara 3 takes place in the updated upper based on uniform breathable AIRmesh with few elements (stitched around the heel, fused in the forefoot) on top of it to provide a custom fit without irritation. Internal stripes (DynamotionFit) wrap the foot following its movement featuring a more secure transition.
Rest of Sayorana 4 keeps what was working fine with moderate thick midsole to provide enough shock absorption with extremely light U4ic compound combined with well known Mizuno's Wave™ for a firm but cushioned ride. Outsole features X10 rubber in high wear areas longer durability and lightweight blown rubber in the forefoot for smoother ride.
