Tecnica Mach Boa

The BOA system uses a dial-actuated cable to wrap the shell evenly around your foot, eliminating the pressure points often caused by rigid buckles. It provides a more precise, micro-adjustable fit that you can tighten or loosen on the fly without needing to unbuckle.

A 105 flex is designed for intermediate to advanced skiers who want a balance of responsiveness and comfort. It offers enough stiffness to transfer energy efficiently for aggressive carving, but it isn't so rigid that it becomes punishing during a full day on the mountain.

C.A.S. stands for Custom Adaptive Shape, which means both the plastic shell and the inner liner are heat-moldable. This allows a boot fitter to customize the shape to your specific foot anatomy, significantly reducing the likelihood of hot spots or discomfort.

Yes, the Quick Instep construction uses softer plastic in the throat of the boot, making it much easier to slide your foot in and out. This is a noticeable improvement over traditional, stiffer boot designs, especially in cold temperatures.

With a 100mm last, this boot is considered a medium-volume fit. It is designed to accommodate the average foot shape, offering a secure hold without feeling overly restrictive or too loose.
