Crafted for dynamic workouts — from HIIT sessions and mountain climbers to short runs and agility drills — the Cloud X 4 offers ultra-flexible performance and stable support. Its standout features include an X‑shaped Speedboard® that enhances forefoot flexibility, a Helion™ super‑foam midsole for plush yet durable cushioning, and a midfoot cage with star‑lacing system that locks your foot in during lateral movements. The lightweight, recycled mesh upper (90%+ recycled polyester) paired with plush heel and tongue padding ensures comfort. A rubber outsole delivers reliable traction during side‑to‑side action, while a 7 mm heel-to-toe drop gives a balanced, responsive feel. Weighing around 286-288 g (10.1 oz), it’s sporty yet agile — ideal for multi-workout routines.
