Scarpa MAESTRALE RS ski boot is the perfect blend of performance and backcountry functionality. The RS utilizes a bi-injection carbon-infused Grilamid Lambda Frame shell to add power and rigidity without adding weight. The Thor cuff, which now utilizes Grilamid Bio - a planet-friendly, renewable resource - also increases torsional rigidity while providing a 60-degree range of motion for long efficient strides. The HRS strap keeps your heel planted where it should be to increase performance and comfort on the way up and down while the lower Wave Closure system provides the same security as a 2-buckle system at a fraction of the weight. The glove-friendly Finger Strap features RECCO Technology for increased avalanche searchability. The Maestrale RS is for experienced backcountry skiers looking for uncompromising performance.
