The 4-Quattro Pro Limited Edition is built for those who redefine what's possible in the mountains. Engineered around a Pebax® Rnew® shell and cuff, it earns its place as the lightest high-performance freeride boot on the market, delivering a flex index of 130+ and a forward lean of 19° without compromising a gram of responsiveness. Inspired by Nikolai Schirmer’s groundbreaking high-altitude freeride descent, this limited edition bridges the gap between resort-level power and backcountry mobility. The Secure Speedlock 4 ski/walk mechanism enables fast, reliable transitions on technical terrain, while the PRESA® SKI-01 / GripWalk Tour outsole (ISO 23223 certified) provides confident traction from boot packs to groomed runs. Inside, the Intuition® 4Pro Flex Ride liner wraps the foot in a heat-moldable, performance-tuned fit across a 100mm last, precise enough for aggressive charging, comfortable enough for long days in the field. This is a limited edition release for riders who don't wait for the trail to be broken.
