On Cloudrunner 2 Waterproof - Black - 4 UK

The Cloudrunner 2 Waterproof features an upgraded Helion Superfoam midsole for a softer feel and higher energy return, an improved outsole designed to prevent stone pick-up, a plusher tongue, and uses 100% recycled polyester for the entire upper, significantly enhancing sustainability.

While durable, these shoes are primarily designed for road running. The outsole provides good traction on paved surfaces and light, well-maintained trails, but for aggressive or technical trail running, a dedicated trail shoe would be more appropriate.

Gently brush off loose dirt. For deeper cleaning, use a mild soap and cold water with a soft brush or cloth. Avoid machine washing, harsh chemicals, and tumble drying. Always allow them to air dry naturally.

The 10mm offset refers to the difference in height between the heel and the forefoot. A higher offset like 10mm typically promotes a more heel-strike dominant gait and can provide more cushioning under the heel, which many runners find comfortable for longer distances.

Yes, you can. However, the waterproof membrane, while breathable, may make the shoe feel slightly warmer than a non-waterproof running shoe in very hot conditions. They are most beneficial in cool, damp, or wet environments.

The On Cloudrunner 2 Waterproof weighs 230g for a women's size 4 UK. Weights for other sizes may vary slightly.

Ensure the shoe opening is properly sealed around your ankle (e.g., by wearing waterproof trousers over the collar) to prevent water from entering from above. Also, check for any accidental punctures or damage to the waterproof membrane, though this is rare.

Running shoes have a lifespan, typically 300-500 miles, after which cushioning materials can degrade. If you're within this range, ensure proper drying and storage. Beyond this, it might be time to consider replacing them.

While the outsole is redesigned to minimize stone pick-up, smaller debris can occasionally get lodged. Regularly inspect the outsole and gently remove any trapped stones to maintain traction and prevent wear.

The Cloudrunner 2 Waterproof is designed as a structured shoe for support. Allow for a break-in period. If discomfort persists, consider trying different lacing techniques or wearing thinner socks to reduce bulk, though it might indicate a preference for a less structured shoe.
