Some say the Salomon S-Lab Skate Boot was designed in a secret underwater laboratory by fugitive Martian scientists. We couldn't possibly comment on that rumor, but we can say plenty about the S-Lab, Salomon's high-end skate boot. Lighter than even the top-of-the-line S-Lab Pro, the Skate has a carbon 3D chassis and an underfoot carbon skating plate, which work together to provide superior torsional rigidity and power transmission while minimizing weight. The sole features Salomon's RS17 technology, which moves the front axis of the famous double pivot 17mm behind the front of the boot, putting it under the forefoot to keep the ski tighter to your foot for increased control and responsiveness. When you're going full-out V2 across the flats or crushing the ups, you don't want a soft cuff that soaks up energy and lets your ankle flop around. To that end, Salomon's 3D Energyzer provides lateral ankle support, while allowing your foot and ankle to relax, reducing tiredness. It also functions as a spring, compressing when weighted and rebounding when unweighted to drive the ski forward and lift the tip for a drag-free step and quicker ski return. You won't sweat the downhills, either, thanks to the full-length guide ridge, which aligns with the groove in the Skate's outsole to lock your foot in place, providing top-class stability. The S-Lab also offers unparalleled fit, thanks to foam that will naturally mold to your foot as you wear the boot. A 100mm racing last closes with the Quicklack system, a hook-and-loop strap hugs the ankle, and you can fine-tune heel hold with an adjustable strap in the rear of the boot. To keep you warm, dry, and focused on racing, the diagonal-zip lace cover has bonded seams to repel water.
