Surround your foot with better breathability and waterproof protection.
The La Sportiva Men''s Synthesis Mid GTX Hiking Boot feels surprisingly breathable for a shoe equipped with waterproof protection. That''s because Gore-Tex''s latest-and-greatest Surround technology allows 360-degree breathability. Compared to previous waterproof, breathable membranes that only cover the shoe''s upper, Surround technology wraps a membrane around the upper and sole. You''d think this would decrease the shoe''s overall breathability, but La Sportive fused a sole with mesh inserts that enhance the shoe''s breathability while still providing a truly waterproof experience.
The Synthesis also features a well-ventilated AirMesh upper with Nano-Cell technology for better support. STB technology unifies the midsole to the upper for a longer lasting performance, and the PU leather toe protects your foot from protruding rocks. Underfoot, the Synthesis uses a cushy compression-molded EVA midsole with cradling TPU inserts that keep your foot prime for miles. A shoe this good deserves the best sole, which is why La Sportiva used Vibram''s superlight Nano rubber, and there''s also an Impact Brake System for an improved downhill performance.
