What Our Gearhead(R) Experts Are Saying: "I wore the Cloudultra 3 during a weekend in the Tetons and never once felt like I needed to switch shoes. The grip was solid on scrambles, and the cushion held up mile after mile. It's that rare combo of light, tough, and ready for anything."When we're planning an all-day mission through alpine singletrack, we want gear that won't quit. That's why we lace up the Cloudultra 3 Trail Running Shoe. Designed to stay comfortable and responsive over ultra-distance runs, it brings together the best of cushion, control, and lightweight breathability for high-performance on high-output days. The reengineered Missiongrip(TM) outsole sticks to technical rock and loose gravel alike, while a layer of Helion(TM) HF hyperfoam keeps each step energetic and smooth. Its Leno woven mesh upper delivers flexible structure and fast-drying airflow. Add in a forefoot rocker and secure step-in fit, and you've got a shoe that makes even the longest trail days feel surprisingly effortless.
