Questions answered
FAQ
Is the Cloudultra good for ultras?
Yes, it is specifically designed for ultra-distance trail events. The Helion foam maintains cushioning over long distances and the Missiongrip outsole handles varied mountain terrain. Well-reviewed by ultra runners.
How does the Cloudultra compare to the HOKA Speedgoat?
Both are popular ultra trail shoes. The Cloudultra offers a firmer, more responsive ride, while the Speedgoat is softer and more cushioned. The HOKA has wider appeal; the On appeals to those who prefer a more connected ground feel.
Do the Cloud pods cause issues on trails?
The pods can trap small rocks and debris, which is a known On Running issue. On trails with loose gravel, you may need to stop and clear them occasionally. The Missiongrip outsole otherwise performs well.
Does the Cloudultra run true to size?
Yes, with a snug heel and roomier forefoot. The fit allows toes to splay on descents, which is important for ultra distances. True to size works for most runners.
