Why Choose the Cloudboom Max

CloudTec®‑like cushioning flows into Helion™ foam for soft landings, while the Speedboard® adapts to your pace — it feels tuned, not twitchy. In long races, stability and comfort outlast lighter, more fragile racers.

Heel Cushioning: Extra padding in the rearfoot softens every landing. Keeps your stride consistent even late in the race.
Supportive Fit: The upper molds to your foot as you move. Delivers stable lockdown without pressure or hotspots.
Road Grip: The rubber outsole grips well even on slick tar. Keeps transitions steady across uneven road surfaces.
Built for Distance: Designed for four-hour marathon efforts and beyond. Maintains structure and comfort over time, not just speed.
