High speed on any path: Rukka Ragusa is the pinnacle of versatility, handling smooth or rocky as well as wet or dry surfaces. The sock-like shaft helps keep stones and debris out of the shoe. The ARMORTEX® upper reinforced with DuPont™ Kevlar® fibers is slip-resistant and durable. The material provides the flexibility, durability, and resilience required for varying outdoor use. The shoe's water-repellent A.W.S. WATER-RESISTANT surface protects feet from light rain and splashes, enhancing comfort. The water-repellent treatment also speeds up the drying of the surface materials.
