SKI BOOTS

Ski boots come in several types: alpine (downhill) boots for resort skiing, alpine touring (AT) boots for backcountry and uphill travel, freeride and freestyle boots for mixed terrain and park features, and Nordic boots for cross-country skiing. Each type is designed for specific skiing styles and binding compatibility. 

A proper ski boot fit should be snug but not painful, with your toes just touching the end when standing upright and your heel secure when flexing forward. A good fit improves control, reduces fatigue, and prevents blisters. Many boots offer customisable liners and micro-adjustments for a tailored feel. 

Flex refers to the stiffness of the boot, measured by a flex index. Lower numbers (60–90) are softer and best for beginners, while higher numbers (100+) are stiffer for advanced skiers. Choose flex based on your weight, skiing ability, and preferred terrain - a stiffer boot offers more control at higher speeds. 

Not all ski boots are compatible with every binding. Alpine boots use ISO 5355 soles, touring boots use ISO 9523, and some feature GripWalk or Walk-to-Ride soles. Always check that your boots and bindings are compatible, especially when mixing alpine and touring equipment. 

Look for features such as adjustable buckles, power straps, walk modes for easier walking, moldable liners for a custom fit, and replaceable soles for durability. Touring boots may also have tech fittings for pin bindings and lighter construction for uphill efficiency.
