Do ski boots come in half sizes?

Ski boots are available only in full-size increments, meaning a 25.0 and a 25.5 boot will be the exact same size and fit. All of our boots are listed in full sizing ending in .5.


Ski Boot Width

Ski Boot Last

The width of a ski boot is measured at its widest part, across the forefoot, and is expressed in millimeters. This measurement is commonly referred to as the "last." The last represents the width of the boot's interior at the ball of the foot. Understanding the last is crucial in ensuring a comfortable and well-fitted ski boot. Ski boot width is categorized into three main ranges: narrow, medium, and wide

Narrow Last (typically 98mm and below):

Boots with a narrow last are designed for skiers with slimmer feet. These boots provide a snug fit, offering precise control and responsiveness. They are suitable for advanced skiers who prioritize performance and quick edge-to-edge transitions.

Medium Last (around 99-101mm):

Boots with a medium last are considered all-mountain options, catering to a broader range of foot shapes. This category offers a balance between comfort and performance, making them suitable for a variety of skiing conditions and styles.

Wide Last (102mm and above):

Boots with a wide last are crafted for skiers with broader feet. These boots provide ample space, promoting comfort and warmth. They are ideal for skiers who prioritize a more relaxed fit and spend extended periods on the slopes.

The last measurement is a key factor in determining how a ski boot will fit and feel on your foot. It's important to choose a last width that matches your foot shape to ensure proper support, control, and comfort while skiing. Skiers should consider their foot width, arch height, and overall comfort preferences when selecting the appropriate last for their ski boots.


Ski Boot Flex

Boot flex refers to the stiffness or flexibility of a ski boot and is an important factor in determining how responsive and supportive the boot will be during skiing. The flex rating is often expressed as a number, with higher numbers indicating stiffer boots. Understanding boot flex is essential for selecting the right pair based on your skiing ability, style, and preferences.

Soft Flex (70-90):

Boots with a softer flex are more forgiving and accommodating, making them ideal for beginners and skiers who prioritize comfort over aggressive performance. Soft-flex boots are easier to control and allow for a more relaxed skiing experience.

Medium Flex (90-110):

Boots with a medium flex are versatile and suitable for a wide range of skiers. They provide a good balance between responsiveness and comfort, making them well-suited for intermediate and advanced skiers who enjoy a mix of groomed runs and varied terrain.

Stiff Flex (110-130+):

Boots with a stiff flex are designed for advanced and expert skiers and racers seeking maximum precision and control. These boots offer excellent responsiveness, especially at higher speeds and on challenging terrain. Stiff-flex boots are commonly preferred by aggressive skiers and those who prioritize performance.

When selecting ski boots, it's important to match the flex rating with your skill level, skiing style, and the type of terrain you plan to tackle. A proper boot flex ensures optimal power transfer from your legs to the skis, enhancing your overall skiing experience. Beginners may benefit from a softer flex for comfort and ease of learning, while advanced skiers may prefer a stiffer flex for increased control and performance.
