The Altas 930 FRS Snowshoes uses the patent-pending Free-Rotating™ Suspension (FRS) for natural articulation of the foot over uneven and sidehill terrain with minimal resistance which provides the most comfortable, forgiving stride. FRS flexes the 6061 aluminum proprietary V-Frame with each step, gives the toe traction deeper purchase. The flexible Wrapp™ bindings tighten easily and cradle the foot securely. Even in the dead cold of winter, the Nytex decking is both flexible and durable. Whether you’re new to snowshoeing or a seasoned pro, the 9 Series FRS is built to explore winter’s rolling terrain.
