We took the all-day comfort and all-mountain versatility of our award winning Speedmachine and fused it with the DNA of our top-of-the-line Dobermann race boot. The result: The power you demand and the comfort you desire. The entire line of Promachine boots, which comes in a 130, 120, and 110 flex, are the lowest-volume, most modern lightweight design that we've ever created. All of the boots in the line are fully customizable, making for unparalleled responsiveness and precision. For a boot that combines performance with all-day comfort, look no further than the Promachine.
