La Sportiva Men's TX4 Evo ST

The TX4 Evo ST’s synthetic upper provides exceptional breathability, while an EVA midsole ensures outstanding protection and cushioning on tricky trails and via ferrata routes. The lacing system also allows a precise fit. On slippery descents and challenging uphills, the Vibram® MegaGrip compound sole with patented Impact Brake System™ tread pattern guarantees maximum stability and reliable traction control. As your route gets technical, experience ultimate precision and a superior grip thanks to the generous Climbing zone on the toe. The patented Resole Platform™ insert means these can be resoled without affecting comfort and performance, so you can explore the mountains in your TX4 Evo STs year after year. Impact Brake System Mountain Running: The innovative system is applied to the sole to absorb negative ground impact, help traction and improve grip downhill.  Created and developed by the R&D department at La Sportiva, it offers real advantages during racing by reducing negative ground impact. The unique position of the lugs allows as many of them as possible to come into contact with the ground, for maximum impact absorption.
