The Grivet Take
The Cloudmonster 3 is On's max-cushion daily trainer for runners who want the tallest stack On makes. Triple-layered CloudTec produces 41/35 stack with a 6mm drop, an aggressive forefoot rocker, and a wide platform that reads steady underfoot. Best for daily easy miles, long runs, recovery days, and walkers who want premium On cushion. Skip it for speed work; the geometry is built for cruise pace and protection, not pace.

Support
Support TypeSupport Type describes how much built-in guidance the shoe has. Neutral shoes do not add support structure. Stability shoes use geometry, rails, firmer foam, or frame designs to create a more guided feel. Motion control shoes are the maximum-support category and are rare in modern running.

Wider, steadier base
How it fits
Fits true to size with a standard On last. Toe box runs standard width with normal vertical room. Midfoot is normal volume; heel hold is good. Available in Standard (B) only for women's.
How it feels
Cushion is at the top of the scale; triple-layered CloudTec produces On's distinctive forward-rolling feel with maximum stack for long-day protection. The 6mm drop and aggressive forefoot rocker carry the foot smoothly through toe-off. Energy return is moderate; the foam protects more than it propels.
