On Cloud X FKA | Triple Black | 3WF10700553

Performance Engineering. Total Blackout.

The On Cloud X FKA (3WF10700553) in Triple Black is the most striking colorway in the Cloud X FKA lineup — a full-blackout multi-purpose trainer that turns On’s most technically layered shoe into a single, unified statement. Every surface — the engineered knit mesh upper, the organic suede overlay panels, the open CloudTec® midsole pods, the rubber outsole — rendered in the same deep, matte black. The result is a shoe where the architecture becomes the aesthetic: the flowing, sculptural overlay panels that define the Cloud X FKA’s silhouette read as shadow and depth rather than color contrast, making this the version of the shoe that rewards a second look. The hidden Speedboard™ plate and open CloudTec® cushioning system perform identically to every other Cloud X FKA — the only difference is that this one disappears into any outfit and announces nothing.

Product Highlights

• 🎨 Colorway: Triple Black Tonal — black engineered knit mesh, black suede overlays, black CloudTec® midsole, black rubber outsole in a fully unified all-black palette
• 🧵 Engineered Knit Upper with Recycled Polyester: Lightweight black engineered knit mesh upper constructed with recycled polyester fibers — breathable, flexible, and sustainably made, with a multi-layer mesh texture that adds visual depth and dimension to the all-black colorway
• 🧤 Sculptural Suede Overlay Panels: Organic, flowing suede overlay panels at the toe cap and lateral sides — the Cloud X FKA’s defining design detail, with curved, three-dimensional forms that create shadow and depth against the mesh base, providing targeted structural support while defining the shoe’s distinctive silhouette
• ⚡ Hidden Speedboard™ Plate: On’s exclusive concealed Speedboard™ carbon-composite plate embedded within the midsole — engineered to store and release energy with each stride, propelling you forward with a responsive, spring-like toe-off that transforms every step into forward momentum
• 💨 Open CloudTec® Cushioning: On’s signature open CloudTec® cushioning pods in the midsole — individually compressing on impact to absorb shock across the full footstrike, then snapping closed at toe-off to work in concert with the Speedboard™ plate for maximum energy return
• 🔶 Black Rubber Outsole: Durable black rubber outsole with multi-directional traction pattern — providing reliable grip on road, gym, and light trail surfaces, completing the shoe’s all-black tonal palette from upper to ground
• 🏷️ Style Code: 3WF10700553

The Cloud X FKA Story

The On Cloud X is the brand’s most versatile training shoe — engineered for the athlete who moves between the gym, the road, and the street without changing shoes. The FKA edition takes this platform and elevates it with a design-forward upper construction: recycled engineered knit mesh, sculptural overlay panels, and a hidden Speedboard™ plate that delivers elite-level energy return in a lifestyle-ready silhouette. The Triple Black colorway strips away color entirely, leaving only the architecture — a shoe that is as much about form as it is about function.
