Tecnica Mach1

The High Volume (HV) designation indicates that this boot is built on a wider last, providing more room in the forefoot and instep. It is specifically designed for skiers who typically struggle with pressure points or tightness in standard-width boots.

A 110 flex is generally considered stiff, making it ideal for advanced to expert skiers who prioritize power transmission and responsiveness. If you are an intermediate skier looking to progress, this boot will provide the stability you need, but it will be less forgiving than a softer-flex model.

Yes, these boots are compatible with ISO 23223 Gripwalk bindings, which are standard on most modern alpine setups. If you are using older, non-Gripwalk compatible bindings, you should verify compatibility with a technician before use.

The C.A.S. system uses a pre-shaped anatomical shell and liner that can be easily punched or ground by a boot fitter to address specific hot spots. This allows for a highly personalized fit that contours to your unique foot shape without compromising the shell's structural integrity.

The Quick Instep feature uses a softer plastic material over the instep area, which allows the shell to open wider than traditional boots. This makes getting in and out of the boot significantly easier, even in cold temperatures when plastic tends to stiffen.
