La Sportiva TX4 EVO ST W'S ZFAS050R25G19 Redwood/ONYX The TX4 Evo ST W Redwood/Onyx combines the features of hiking and climbing shoes, providing durability, lightweight performance, and grip. The upper is constructed from high-strength mesh (HT TPU) with the addition of recycled PES fibers, reinforced with a rubber toe cap and rubber overlay. This construction provides breathability and abrasion resistance. A 4mm Ortholite Hybrid Approach footbed provides comfort on longer runs, while a MEMlex midsole with a TPU frame and ~7% EVA offers cushioning and stability. The Vibram MegaGrip outsole with Impact Brake System and Climbing Zone provides excellent traction on ascents and descents. The STB Control System™ improves gait control without increasing stiffness underfoot. Thanks to the Resole platform, the shoe can be re-treaded, extending its lifespan. At approximately 405g (per pair), it's a relatively lightweight yet durable approach shoe for women who take technical trails seriously.
