Touring ski boots are specialized footwear designed for backcountry skiing and uphill travel. These boots typically feature a lightweight construction and incorporate a walk mode for improved range of motion while skinning uphill. Many touring boots have tech fittings for compatibility with pin-style bindings. When selecting touring ski boots, consider factors like weight, flex, range of motion, and intended use - whether that's long backcountry tours or a mix of resort and sidecountry skiing. A proper fit is crucial for comfort and performance, so trying on multiple models is recommended.
