On Cloudswift 4 AD - Grey - UK 8.5

The Cloudswift 4 AD is designed as an everyday neutral running shoe, ideal for daily training, urban runs, and varied distances. Its cushioning and weather protection make it versatile for most non-technical running environments.

No, they feature a water-repellent finish on the mesh upper, which provides protection against light rain and splashes, keeping your feet drier in damp conditions. They are not fully waterproof for submersion.

Helion superfoam is On's proprietary cushioning technology. In the Cloudswift 4 AD, it's a dual-density foam designed to provide soft landings, powerful take-offs, and high energy return, ensuring comfort and responsiveness.

The nylon-blend Speedboard is a plate embedded in the midsole that works with the Helion superfoam to help propel you forward. It stiffens the shoe for a more efficient toe-off and responsive feel, contributing to energy return.

Gently wipe the upper with a soft, damp cloth and mild soap. For the outsole, use a brush to remove debris. Always air dry at room temperature away from direct heat or sunlight.

While listed with a 'Male' gender attribute for this specific variant, running shoe designs often cater to a broader audience. It's best to consult the size guide and try them on to ensure a comfortable fit regardless of gender.

The upper is constructed from a combination of textile and synthetic materials, featuring a breathable mesh with a water-repellent finish.

Ensure you are wearing appropriate moisture-wicking running socks. While the upper is breathable, prolonged use in very hot, humid conditions or with thick socks can lead to warmth. Consider lighter socks.

The water-repellent finish can wear off over time or with frequent exposure to mud/dirt. After cleaning, you may consider applying a shoe-specific DWR (Durable Water Repellent) spray designed for textile and synthetic materials to refresh the protection.

Running shoes have a lifespan, typically 300-500 miles, after which the cushioning and responsiveness (like the Helion superfoam and Speedboard) can degrade. Track your mileage and consider replacement if they feel worn out.

Check your lacing technique to ensure even pressure across the foot. The sock-like construction is designed for a snug fit, but individual foot shapes vary. Try different lacing patterns to relieve pressure points. Ensure your socks are seamless and well-fitting.
