It delivers more lightweight cushioning, while also helping the shoe shed some of the weight it gained in the 38th version. The big change to the midsole is that Nike added an air unit in the shoe’s heel to accompany the one in the forefoot. The 39th Peg upholds its legendary descriptor as a capable “workhorse with wings.” Like the Pegasus 38, this version uses a React foam midsole it’s not as light and bouncy as ZoomX, but feels medium soft, and moderately flexible. “Smooth and springy, this shoe makes a comfortable ride for endurance work and longer runs when you’ll be spending a lot of time on your feet,” one tester said. Strictly Enerzy foam throughout makes the ride smoother and more consistent-especially when paired with the 25’s new castor bean-based wave plate.īuilt at a higher amplitude (the Rider 24’s plate was flatter), it helps return more energy with each footstrike, and more comfortably matches the shape of the arch. Though comfortable underfoot, the combination of multiple foams could make the shoe’s ride feel a bit disjointed with messy transitions. In previous Rider midsoles, Mizuno mixed and matched a handful of foams-ranging from its firmer U4ic to U4icX-both above and below the wave plate.

Part of that is because the brand delivered on the promise that it teased us with in the Rider 24: a full-length midsole layer of luxuriously soft Enerzy foam. One longtime tester pegged this one as his favorite yet, and another said it’s definitely the softest and most cushioned. Twenty-five marks a huge milestone for the Rider, and that’s not just because Mizuno has now filled a quarter century with models of this shoe. Throw in some stability features-an external TPU heel counter, wider platform, and secure lacing system-and you have a well-rounded trainer that locks in your foot and guards against ankle rolling. “It was like running in a soft moccasin that held your foot secure without any unwanted motion.” The Phantom’s coziness puts it in the same class as the Brooks Glycerin and Altra Paradigm. “I found the cushioning to be top-notch from front to back,” said one tester who’s a self-described heel striker. But the standout feature is the two-piece midsole, which provides firm cushioning and shock absorption-perfect for high mileage and runners with an aggressive cadence. Some testers scoffed at the appearance of such a wide toebox, but appreciated how its odd shape prevented black toenails and blisters.

Preserving the original’s traits, the new Phantom provides an accommodating fit with a generous amount of toe room.
