Hiking shoes Scarpa BOOSTIC size 38.5 Black-Azure, weight 235 g

Scarpa BOOSTIC climbing shoes in size 38.5 combine a multi-panel microfiber upper with an Alcantara insert over the big toe for comfort. An elastic gusset eases foot entry and dual Velcro straps secure the fit. The shoe features a differentiated tension system and a PAF heel construction to optimise force distribution, a minimal 1 mm Flexan midsole for sensitivity, and a full-length Vibram® XS EDGE rubber sole 3.5 mm thick for support on small edges. The model can be resoled at authorised service centres to extend its useful life.

Advantages

The multi-panel microfiber upper with Alcantara at the toe offers a balance of comfort and precision. The DTS (Differentiated TENSION System) concentrates force toward the big toe without compromising fit, while the PAF heel construction reduces pressure on the Achilles tendon and improves force distribution. A thin Flexan insert enhances ground sensitivity and the Vibram® XS EDGE outsole provides stable support and reliable friction on small holds. Dual Velcro straps and an elastic gusset provide easy entry and a secure, adjustable fit.

Suitable for

• Sport climbing on small edges and technical routes
• Indoor bouldering and gym sessions requiring sensitivity
• Climbers who prefer a moderately stiff shoe with precise toe power

When it may not be suitable

This shoe’s design focuses on sensitivity and toe power rather than maximal cushioning, so it may feel firm for long approaches or all-day multipitch climbs. Climbers seeking a very soft, highly downturned performance shoe for extreme edging or aggressive hook moves might prefer a different model.

How to use

Put the shoe on by easing the foot through the elastic gusset, then fasten the dual Velcro straps to achieve a snug but comfortable fit. Use the differentiated tension system by positioning the foot so the big toe can engage the concentrated tension area for effective power transfer on edges. Maintain precise foot placement on holds to benefit from the Vibram® XS EDGE outsole and the thin midsole that maximise sensitivity.

What to consider before purchase

• Fit preference: moderately stiff, sensitive shoe—try for correct sizing and comfort
• Intended use: optimized for edging and technical indoor/outdoor climbing rather than long approaches
• Resoling: model can be resoled—plan maintenance to preserve performance

Usage recommendations

For best performance, wear these shoes on technical routes and bouldering problems where toe precision and edge support are required; resoling when rubber wear becomes significant will extend the shoe’s life and preserve stability.
