Sala is a light but warm winter boot designed for comfort. Its notably soft upper is made of quilted polyester, a durable and water-repellent textile made from recycled Ripstop polyester. A mudguard at the bottom of the shoe protects it from slush, water, and dirt. This makes the shoe easy to maintain and extends its lifespan. The shoe's zipper is located at the front, making it easy to put on and take off. The non-studded Nordic Traction™ outsole rubber keeps its excellent properties also in low temperatures.
