On Running Cloud X4

The On Cloud X 4 sneaker is the successor to the popular Cloud X series, designed for versatile athletic performance and everyday comfort. This running-inspired shoe features On's signature CloudTec cushioning system with Helion Superfoam, providing responsive shock absorption and energy return during dynamic movements. The technical mesh upper ensures breathable support with strategic reinforcement in high-stress areas, while the Speedboard technology enhances propulsion and stability during heel-to-heel transitions. Weighing approximately 240 grams per shoe in size EU 39, the Cloud X 4 maintains a lightweight construction without compromising durability. The outsole integrates mission-specific rubber placement for optimal grip on various surfaces, from indoor training floors to outdoor running paths. The internal construction includes a molded heel area and padded collar for secure foot positioning, complemented by a removable insole that can accommodate custom inserts if needed. Available in several color options, this model continues the brand's commitment to Swiss engineering precision and functional design. The Cloud X 4 is suitable for cross-training activities, short-distance runs, and daily wear, offering a balanced combination of cushioning, responsiveness, and support. The design incorporates reflective elements for improved visibility in low-light conditions while maintaining the practical approach characteristic of the brand's performance shoes.
