If primates had evolved with sticky rubber on their feet, you and I would’ve been born wearing the Booster S. Sensitive, light, and supple, the Booster S is a softer version of the Boostic – it’s designed for steep bouldering, wicked gym sessions, and anything overhanging. Tri-Tension Active Randing concentrates power and focus in the toebox and SCARPA’s fit stays precise for the life of the shoe. Pull it on and evolve into the Booster S. • 1/3 Length Sole • Tri-Tension • Ultra Thin Support Ribbon • Upper: Microsuede • Midsole: Flexan 1.0 • Sole: Vibram® XS Grip 2; 3.5mm • Last: FZ • Weight: 200g; 7oz (1/2 pair size 40)
