The Hydrogen GTX is a Scarpa offering designed for hikers who require a burst of speed in their step. Its protection from external moisture is courtesy of Gore-Tex.

Allowing users to cut through the ruggedness of the terrain with enough cushioning and security is the footgear’s Salix sole unit. Push offs are enhanced on this unified sole as it comes engineered with a rockered toe.

Scarpa’s Hydrogen GTX is a low-cut, fairly true-to-size speed hiking shoe for men and women. Its sizing selection consists of full and half sizes. It is offered in standard width. Owners may customize its fit for a secure lockdown with the use of the shoe’s ghillie lacing.

Vibram XS-Trek is the rubber outsole promising surefootedness in the Scarpa Hydrogen GTX. Its surface is covered with aggressively shaped self-cleaning lugs for extra sticking power over tricky terrain. Scarpa designers engineered both its heel and forefoot zones with ridges to increase its effectiveness on descents and ascents.

This speed hiker is equipped with a medium-density EVA (ethylene-vinyl acetate) midsole to provide its wearers with adequate cushioning and a steady balance on the trail. It is capable of stabilizing the foot during twisting motions thanks to its anti-torsion plate made of TPU (thermoplastic polyurethane).

The underfoot comfort offered by this stout yet flexible layer is bolstered by the P-Flex Lite + Spacer insole. Its 3.5-mm thick body is built with a combination of rubber and polypropylene.

Sporting the Scarpa Hydrogen GTX means being seen in its below-the-ankle upper made mostly of mesh fabric. Making it sufficiently waterproof on the outside yet breathable all over is Gore-Tex’s Surround technology. Thermo-welded TPU overlays cover its sides for abrasion protection and enhanced lateral support. It also comes built with a supportive heel counter and a sturdy rubberized toe cap.

The footgear’s lace-up closure uses a flat lace made of a synthetic material. Its lace holes are a combination of fabric loops and plated eyelets.
