La Sportiva TX4 Evo ST

Our TX4 Evo ST has the perfect combination of innovative features and lightweight comfort for technical approaches.

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.
