Scarpa Men's Maestrale RS Alpine Touring Boots:

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 also 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.
