On Running Cloudultra Pro

The On Cloudultra Pro running shoes in gray, size 40, are designed for female runners seeking a balance between cushioning and responsiveness during long-distance training. These performance shoes feature On's proprietary CloudTec cushioning system with Helion superfoam, providing adaptive shock absorption that reduces joint stress while maintaining energy transfer for efficient stride transitions. The integrated Speedboard technology in the midsole offers a propulsive feel that supports the natural running motion from heel strike to toe-off. The upper is made of lightweight, breathable engineered mesh with strategic reinforcement zones that provide secure support without restricting movement, complemented by a padded tongue and collar for increased comfort during extended wear. The outsole utilizes Missiongrip rubber with a multidirectional lug pattern for reliable traction on road surfaces and light trails, ensuring stability in various running conditions. The design includes a heel cap for rearfoot stability and an integrated tongue to protect against dirt. Weighing approximately 285 g per shoe in size 40, with a stack height of 32 mm at the heel and 26 mm at the forefoot, these shoes offer a balanced 6 mm drop that accommodates various running styles. The Cloudultra Pro model represents an evolution in On's performance running collection, incorporating feedback from endurance athletes to refine durability and comfort features for training beyond typical distances.
