Technology and construction: CloudTec, propulsion plate, and reactive midsole

The base of these shoes is a midsole designed to offer continuous energy return. Every stride feels propelled, ideal for steady paces in long-distance events.

CloudTec and propulsion plate

CloudTec provides adaptive cushioning: it absorbs impact and releases energy on takeoff. The propulsion plate stabilizes and responds when you need to accelerate or tackle technical climbs.

High-grip sole

The rubber sole guarantees traction on mud and rock, with lugs and compounds designed for durability without sacrificing weight.

Performance on technical terrain: how do they perform?

On technical trails, the secure fit and reinforced toe and heel structure make a difference. The On Running Cloudultra 2 Undyed White maintain stability on descents and offer confidence on uneven sections.

If you're looking for a trail shoe for long days, its combination of cushioning and grip makes it very versatile for ultra trails and multi-day adventures.

Sustainability and undyed design: less dyeing, more freshness

The undyed mesh not only provides a natural and modern look, it also reduces dyeing processes that consume resources. The result is a fresher, more breathable shoe with a clean aesthetic that fits both trail and urban use.

Style and urban use: pair them with streetwear

Their modern profile and natural tone make the On Running Cloudultra 2 Undyed White perfect for off-trail use. Wear them with joggers, technical jackets, or minimalist looks for an athletic-chic style.

Practical tips: sizing, maintenance, and fit

Size selection

If unsure between sizes, consider your foot strike and technical sock. A slightly loose fit favors long sessions to avoid discomfort on prolonged descents.

Cleaning and care

To clean, remove dry mud and use a damp cloth. Avoid harsh washing to preserve the midsole and undyed mesh. More tips on the product page: see full details.
