Upper
Mesh & microfiber fabric upper wraps round your foot like a sock thanks to the Sock-Fit LW construction system, avoiding pressure points and ensuring maximum comfort and precision fit. Protecting the ankle is the EXO SCARPA construction system. The heel is well stabilized by the iconic TPU band that completely wraps around the shoe.
Sole
PRESA® TRN-04 is a sole dedicated to techincal paths, where grip and precision are essential features. The 5 mm deep arrow lugs designed for the maximum performance on snow and mud terrains, are the most important aspect of the sole design. Their position is studied for creating a series of self-cleaning channels. The outsole compound is SUPERGUM W, highly preforming in winter condition, it assures grip on iced terrain and snow.
Lacing

Technologies
PRESA
PRESA® is SCARPA’s proprietary outsole brand, born out of 80+ years of technical outsole design experience, to deliver the best traction solutions available. IKS technology features seven internal impact absorption “domes” in the outsole and midsole that function just like shock absorbers, compressing upon impact to absorb energy. The impact zones are anatomically mapped to provide additional shock exactly where it is needed the most, while maintained stability outside those zones. The midsole material itself is dual-density EVA, providing additional lightweight shock absorption. Incorporated into the midsole is a Dynamic Stabilizer Torsion frame made of TPU (thermoplastic urethane). The DST frame wraps under the arch and extends back along both sides of the heel, for outstanding rearfoot stability and torsion control. The lug design of the outsole provides confidence-inspiring traction via 4mm deep lugs and SuperGum rubber compound, which balances high friction with durability.
Sockfit LW
On the Trail Running models, the tongue is constructed in a single piece of elastic fabric which allows a light wrap around your feet, offering a snug feel and lateral stability.
Exo
Upper construction system designed and developed by Scarpa. Lateral protections (insert or thermowelded cage) combined with upper, create an exoskleton that better protect, support and contain the foot.
BOA®
BOA® Fit System delivers micro-adjustable, precision fit engineered to perform in the toughest conditions.
