The ON Cloudmonster 3 Hyper in Ivory Linen is On's max-cushioned super trainer, built for long runs and uptempo days alike. A full layer of Helion™ HF hyper foam sits atop On's signature CloudTec® midsole, delivering high energy return and a smooth, rockered ride that rolls you forward stride after stride.
Type: Max-cushioned super trainer (neutral)
Best for: Long runs, daily mileage, and tempo efforts
Midsole: Helion HF hyper foam over CloudTec cushioning
Drop: 6 mm
Fit: True to size, with a slightly wider, secure upper
Available in US men's sizes 7–14. A reflective, premium woven upper rounds out a shoe that feels as good on recovery jogs as it does when you pick up the pace.
Sizing
Length: True to size
Width and toebox: An accommodating, roomy forefoot and toebox with good toe splay, paired with a noticeably narrower midfoot. Standard width only.
Fit notes: The laces lock the upper down well with no heel slippage reported, and the midfoot wrap is secure. Overall volume is on the high side, so runners wanting a snug fit sometimes drop a half size. Note that the available review coverage is for the original Cloudmonster Hyper, so treat this as indicative and try a pair on.
