La Sportiva Stream GTX wandelschoenen - carbon/apple green maat: 43

Moving fast along alpine ridges and forest trails demands footwear that keeps up with your pace. The La Sportiva Stream GTX in Carbon/Apple Green is built for the fast hiker who wants waterproof protection without sacrificing breathability. Its GORE-TEX® Extended Comfort with Surround™ Technology blocks outside moisture while allowing sweat vapor to escape through the sole, so your feet stay dry during high-output ascents and long descents. The abrasion-resistant mesh upper with thermo-adhesive TPU skeleton and rip-stop inserts provides a secure, durable fit, while the compression-molded EVA midsole with anti-torsion insert delivers stability on uneven terrain. The Frixion® Blue outsole with Impact Brake System™ enhances traction and reduces impact, and the Ortholite® Mountain Hiking 5mm footbed adds cushioning. A traditional lacing system with metal hooks lets you fine-tune the fit for all-day performance.
