The Cloudmonster 3 in White Frost is a clean, minimalist take on ON's most cushioned trainer — a bright white upper with subtle frost detailing that works as well post-run as it does on the road.
CloudTec Phase technology delivers a smooth, progressive ride from landing to toe-off, while Helion+ superfoam keeps the stack light and energized. The women's-specific last provides a secure, comfortable fit, and the high-stack rocker geometry makes long miles feel effortless.
Sizing
Length: True to size
Width and toebox: A moderately broad toebox, though measurably narrower than the Cloudmonster 2. Standard width only.
Fit notes: No heel slip or lace bite reported, with a snug, secure heel. The midfoot feels a touch roomy until the laces are cinched, after which it locks down well.
