Shoe Scheppach BOOSTER size 40.5 — Black/Orange, 245 g

Scarpa BOOSTER climbing shoe in size 40.5 combines a microfiber upper formed from multiple shaped panels for a precise, comfortable fit with a dual Velcro strap closure that eases entry and secures the foot. The shoe integrates the DTS – Differentiated TENSION System to concentrate force toward the big toe for controlled power transfer, and the PAF heel construction to improve force distribution and reduce pressure on the Achilles tendon. A minimal Flexan midsole insert with full-length support strips enhances sensitivity, while a Vibram® XS GRIP2 outsole covering one third of the length (3.5 mm thickness) ensures flexibility and reliable friction. The shoe can be resoled at authorized SCARPA resole centres.

Advantages

The microfiber upper with anatomically shaped panels provides a snug fit and comfort during climbs, while the dual Velcro straps allow quick adjustment and stable lockdown of the foot. DTS concentrates tension toward the big toe to help with power distribution and precision, and the PAF system reduces localized stress on the Achilles area. The thin Flexan insert increases ground feel without sacrificing support, and the Vibram XS GRIP2 rubber delivers enhanced grip and consistent performance across temperatures. The shoe’s design also permits resoling to extend service life.

Suitable for

• Indoor bouldering and gym climbing where sensitivity and quick adjustments are needed
• Short to moderate sport routes requiring precise foot placement and edging
• Climbers who prefer a sensitive, moderately stiff midsole with targeted tension toward the big toe

When it may not be suitable

The BOOSTER is designed with a focus on sensitivity and toe-directed tension; it may be less suitable for long multi-pitch trad climbs where more cushioning and a neutral, all-day fit are preferred. Climbers seeking very soft, slipper-like comfort or an aggressively downturned shape for extreme overhangs might find this model limiting.

Key specifications

• Upper: microfiber constructed from multiple shaped panels
• Closure: dual Velcro strap system for entry and lockdown
• Tension systems: DTS (Differentiated TENSION) and PAF heel construction
• Midsole: minimal Flexan insert with full-length support strips for sensitivity
• Outsole: Vibram® XS GRIP2 rubber over one third of length, 3.5 mm thickness
• Weight: approximately 245 g (pair or single as specified by manufacturer)
• Colour: Black with Orange accents
• Resoleable at authorized SCARPA reposers

How to use

Put the shoe on by opening both Velcro straps to allow easy insertion of the foot, then fasten the straps to achieve a secure but comfortable lockdown. Use the differentiated tension system to position the foot so force is concentrated toward the big toe when edging or standing on small holds. The minimal Flexan midsole provides feedback—rely on this sensitivity for precise foot placements while the Vibram XS GRIP2 outsole offers traction on edges and holds.

What to consider before purchase

• Intended climbing style (bouldering, sport, long routes) and preference for sensitivity versus cushioning
• Fit and sizing: shaped microfiber upper and tension systems affect fit—try for secure lockdown without excessive pain
• Resoling availability and expected lifespan if you plan heavy use

Usage recommendations

For best performance, use the Scarpa BOOSTER for short to moderate climbs and bouldering sessions where precision and sensitivity are priorities. Fasten the dual Velcro straps snugly and position the foot to benefit from the DTS and PAF systems; have the sole inspected and resoled at authorized centres before excessive wear develops.
