The Scarpa Booster S is an ultra-light climbing shoe made for the advanced boulderer and sport climber. This shoe is designed to be nimble, dextrous, and precise, for fast-moving on hard problems, with an extremely sensitive design and soft midsole only intended to be tamed by the technical connoisseur overhanging and steep routes.
Powerful and precise as they come, strong feet are a prerequisite for the Booster S. 3.5 mm of rubber is about the thinnest sole you can get on the market, and none of this sensitivity is impaired by a desensitising lining. You’ll be able to feel every micro hold, every tiny crystal, and every subtle but useable feature on the rock and use it your advantage. Vibram XS Grip2 rubber is designed for maximum friction so you can easily grip onto far-away holds and maintain body tension whilst horizontal. And the Tri-Tension randing system has been designed for unimpeded power, driving the the foot’s forces through the toes and onto the hold. Just about every feature to make the horizontal feel more like the vertical.
When sizing the Booster S, bear in mind that the unlined microsuede upper will offer the minimum amount of stretch. Scarpa have also designed it to be fit snugly for the highest performance fit. If you’re looking for a more all-round high-performance shoe, try the Boostic.

VIBRAM XS GRIP2™
Rubber compound built for pure friction, recommended for use where maximum grip is the primary need – bouldering and sport climbing, indoor climbing, or extremely smooth, polished routes.
TRI-TENSION™ ACTIVE RANDING SYSTEM
A rand designed for point-precision shoes, the Tri-tension rand enhances powerful movements through dynamic problems by concentrating the strength of the foot through an asymmetrical support ribbon, driving energy to the forefoot.
