Designed with next-level technology in mind and inspired by observing astronauts weightlessly walking on the moon, ØriginalGrand Ultra is the latest product in the disruptive ØriginalGrand collection, and the next great leap forward in comfort. A high-volume dual-density GRANDFØAM footbed provides a soft initial feel, followed by plenty of energy return on each step. Additionally, an internal stretch bootie wraps the foot in a cozy, sock-like feel, while padding at the shoe's tongue and heel conform for great fit and no break-in required. Every component from the upper design to the foam density is optimized to reduce weight.
