Used Men's Tecnica All Mountain Mach 1 Ski Boots Stiff Flex

These boots are fantastic and built for a strong skier. I had them on the mountain 4-6 times and they perform like no other boot I have every worn. They are simply too small. I will buy the same boot, just the next size up. Symmetric Power Transmission: The revolutionary asymmetrical concept is based on a different thickness of the shell and liner structures. The inside of the shell is slightly thicker and stiffer and the outside of the shell is thinner and more flexible. C.A.S. Liner: C.A.S. has revolutionized ski boots with regards to fit and personalization. The liners are anatomically shaped for optimal comfort and offer great heel hold. The internal part of the liner is shaped to match the foot while the exterior matches and conforms to the shape of the shell. The dual density micro-cell material is durable and easy to customize. The C.A.S. liners are less prone to pack-out maintaining the fit over a longer period of time. C.A.S. Shell: The C.A.S. Shell has an anatomical shape that matches the shape of the foot. This allows for a better out-of-the box initial fit. The dimples on the shell offer less surface tension and facilitate heating, making customizing the shell easier. The shell retains the new shape better and longer. Lift Lock Buckles: Innovative Lift Lock system holds the buckles up and out of the way so they don't catch while getting in or out of your boots. Power Lock Strap: The Power Lock strap provides perfect control and more precise power transmission. The hook eliminates the need to open the strap completely, saving you time. Quick Instep: Utilizes softer plastic over the instep area that allows the shell to open easier as you are entering or exiting the boot. T-Drive: Creates a stronger and more effective connection between the cuff and the shell, that delivers a more consistent flex and reduces plastic deformation. This means that the boots perform better with less effort. They do the work for you so you can ski longer and better.
