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

The foundation of these shoes is a midsole designed to deliver continuous energy return. Every stride feels propelled, making them ideal for maintaining a steady pace in long-distance races.

CloudTec and propulsion plate

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

High-traction outsole

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

Performance on technical terrain: how does it perform?

On technical trails, the secure fit and reinforced toe and heel structure make all the difference. The On Running Cloudultra 2 Undyed White maintains stability on descents and provides confidence on uneven terrain.

If you are looking for a trail shoe for long days, its combination of cushioning and grip makes it highly versatile for ultra-trail races and multi-day adventures.

Sustainability and undyed design: less dyeing, more freshness

The undyed mesh not only creates a natural, modern look, but also reduces dyeing processes that consume resources. The result is a fresher, more breathable shoe with a clean aesthetic that works equally well on the trail and in urban settings.

Urban style and wear: pair them with streetwear

Their modern profile and natural tone make the On Running Cloudultra 2 Undyed White perfect for wear beyond the trails. Pair them with joggers, technical jackets, or minimalist looks for an athletic-chic style.

Practical tips: sizing, maintenance, and break-in

Choosing the right size

If you are unsure between sizes, consider your foot type and technical socks. A slightly roomy fit is beneficial for long days, helping to prevent discomfort on prolonged descents.

Cleaning and care

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