La Sportiva's TX4 Evo ST has the perfect combination of innovative features and lightweight comfort for technical approaches. Its synthetic upper provides exceptional breathability, while an EVA midsole ensures outstanding protection and cushioning on tricky trails and via ferrata routes. The lacing system allows a precise fit every time. On slippery descents and challenging uphills, the Vibram® MegaGrip compound sole with the patented Impact Brake System™ tread pattern guarantees maximum stability and reliable traction control. As your route gets technical, experience ultimate precision and superior grip thanks to the generous climbing zone on the toe. The patented Resole Platform™ insert makes it possible to resole the shoes without compromising comfort or performance, so you can keep exploring the mountains in your TX4 Evo STs year after year.
