Head Formula 100 99477188

The Head Formula 100 is a men’s all-mountain ski boot designed to tackle everything from groomed slopes to mixed conditions. It sits in Head’s Formula line, offering a blend of support and adaptability for skiers looking to explore different terrain without switching gear.

With a flex rating of 100 and a medium-volume, 100 mm last, this boot strikes a balance between firm support and comfortable fit. The mid-volume design accommodates average foot shapes while keeping the foot secure, helping to maintain consistent energy transfer from leg to ski. That combination makes it suitable for skiers who want reliable control without feeling locked into an overly stiff shell.

A flex of 100 falls into the comfort range for men’s ski boots, meaning the shell offers more resistance than beginner models but still flexes enough to reduce fatigue during longer days on the hill. The 100 mm last refers to the width of the forefoot inside the shell—it’s narrower than wide-fit options but not as tight as low-volume race boots—providing a mid-ground that helps with both precision and ease of entry.
