The Nordica Promachine 3 130 S ski boots use a Speed Lace liner to deliver the locked-in ankle fit of a true race lace-up, without ever needing to pull the liner from the shell. A 3Force Frame pairs a lightweight, rigid frame with softer plastic through the cuff and shell, so that lock-in transmits power straight to the ski instead of getting absorbed somewhere in a stiff, punishing boot. A molded 3D Custom Cork heel pocket backs up the ankle lock from below, cutting internal movement at the one spot a loose fit usually shows up first. What Our Gearhead(R) Experts Are Saying:"I charged a full run without once feeling my heel shift inside the shell, and pulling the boot off at the lodge took the same five seconds it always does. That's the part I didn't expect from a boot this locked-in."
