Designed to be as extreme as the athletes who wear it, the GEL-Noosa Tri 8 drops almost an ounce in weight to push every envelope possible. The perforated sockliner and open mesh upper optimize moisture drainage and breathability, secured by new lenticular reinforcements. The optional elastic lace and improved heel and tongue grips make the transition smooth from bike to run, while the Propulsion Trusstic makes transition from midstance to toe-off quick and efficient.
