The Scarpa F1 GT is a men’s ski touring boot built for simplicity and lightness. It’s part of Scarpa’s Speed category, weighing in just under 1.2 kg, and is aimed at skiers who want a reliable boot for uphill travel without carrying extra grams.
This boot features a 100 mm last and mid-volume shell that strike a balance between a snug fit and enough room for longer days on the skin track. With a flex rating of 90, the F1 GT offers enough stiffness for confident turns on the descent while remaining forgiving on steep approaches. The generous 72° range of motion in walk mode makes climbing more comfortable, and at 1 165 g per boot (size 27.5), it stays light underfoot for extended tours.
A flex of 90 sits in the comfort range for men’s ski boots, meaning the shell is stiff enough to give you control when you need it but still has some give to ease fatigue. The 100 mm last refers to the width of the forefoot in millimetres—a mid-width that fits many foot shapes without feeling overly tight. The 72° cuff articulation allows a natural stride when skinning uphill and locks into ski mode for downhill stability.
