THE PROLIGHT TECHLACE'S RIDER-ENHANCING BENEFITS ARE CREDITED TO THREE MAIN COMPONENTS - AN ULTRALIGHT UPPER MADE WITH A TECHNICAL MONOFILAMENT MESH WITH TEIJIN TPU WELDED REINFORCEMENT THAT DOESN'T STRETCH UNDER POWER, THE TECHLACE CLOSURE SYSTEM THAT COMBINES THE COMFORT OF LACES WITH ON-THE-FLY ADJUSTABILITY, AND FINALLY THE TEXTREME CARBON FIBER OUTSOLE. This unconventional composite is woven in flat sheets instead of threads, producing a carbon fiber that's ultra-stiff, yet lighter because it requires less resin. When every gram matters and every second counts, the Prolight Techlace amplifies your performance.
