La Sportiva Stream GTX hiking boots - carbon/apple green size: 46_5

Fast hiking demands a shoe that keeps pace without sacrificing protection—and the La Sportiva Stream GTX answers with GORE-TEX® SURROUND® technology. Unlike conventional waterproof boots that trap heat, this low-cut model channels air through the midsole and outsole for 360° breathability, so your feet stay dry from both rain and sweat. The abrasion-resistant mesh upper with Nano-Cells™ structure balances airflow and durability, while PU TechLite toe and heel caps shield against rocks and debris. A compression EVA midsole with TPU inserts provides stable, shock-absorbing comfort, and the Vibram® XS Trek outsole with Impact Brake System grips confidently on varied terrain. Finished with an Ortholite® Mountain Hiking 5mm footbed and a 10mm drop for natural foot movement, the Stream GTX is built for fast hiking, light trekking, and everyday trails.

Highlights

• GORE-TEX® SURROUND® membrane: waterproof and breathable with ventilation channels
• Vibram® XS Trek outsole with Impact Brake System for superior traction
• Ortholite® Mountain Hiking 5mm footbed for long-lasting cushioning
• Compression EVA midsole with TPU inserts for stability and shock absorption
• Low-cut, comfort fit with 10mm drop for agile movement

In daily use

On the trail, the Stream GTX feels responsive and light. The GORE-TEX® SURROUND® system actively vents heat, while the compression EVA midsole absorbs impact to reduce fatigue over long distances. TPU inserts add torsional rigidity for confident footing on uneven ground. The lace-up closure and comfort fit adapt to your foot, and the low-cut design allows free ankle movement. Whether you're pushing the pace on a fast hike or navigating rocky approaches, this boot delivers performance without the weight.
