On Cloudultra Pro

Craig Randall from iRunFar highlights the On Cloudultra Pro as On’s most mature, race-ready trail shoe yet, praising its plush dual-density Helion foam, innovative Leno-weave upper, and confident handling on dry and mixed terrain. He’s enthusiastic about the shoe’s long-distance comfort and nuanced balance of components—calling it greater than the sum of its parts—and notes its sub-10-ounce weight belies a roomy, stable footprint that suits wide feet and extended ultras. Randall tempers excitement with measured criticisms: propulsion and turnover aren’t as snappy as some plated competitors, wet-surface grip and mud-shedding lag behind Vibram-equipped rivals, and the $260 price is steep. Unique insights include the small, fork-shaped Speedboard, effective lab-and-field prototyping (FEA and hundreds of lug compounds), and real-world race pedigree tied to elite athlete wins—making it a compelling, if not outright super-shoe, option for long mountain efforts.

Better Trail praises the On Cloudultra Pro as a rare blend of race-capable snap and long-haul comfort, calling it one of the most well-rounded max-cushioned trail shoes the reviewer has used. The tone is enthusiastic and impressed—highlighting lively PEBA foam, a fiberglass propulsion plate, planted stability (38.5 mm heel stack), and real-world wins including a 100K—while fairly noting a major downside: the Missiongrip outsole’s shallow lugs wear quickly and lose bite in sustained wet, muddy, or snowy conditions. The review balances high praise for responsiveness, comfort, and upper/midsole durability with concrete usage notes (race and ultra experiences, ~400 miles tested) and pragmatic advice to reserve the shoe for dry-to-mixed terrain or race days because of traction longevity. Overall, it’s an excited endorsement tempered by a clear, recurring caution about tread durability.
