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.
