Salomon S/Pro Delta BOA 120

The S/Pro Delta BOA 120 is a performance all-mountain boot built for intermediate skiers with a wider foot who want stiffness without compromise on comfort. The 120 flex gives you edge control and responsiveness on firm snow, while the 102 mm last—the widest in the S/Pro line—keeps pressure off the sides of your foot through a full day of varied terrain.

Why we rate it

Salomon's BOA Fit System on the lower shell means you can dial in heel hold and edge-to-edge control with precision, without pressure points. The custom heat-moldable shell and My Custom Fit 4D liner both adapt to your foot shape in 10 minutes—the shell wraps exactly where you need support, the liner gives you elastic room in the toe box. The 3-position calf adjuster (neutral, narrow, wide) handles different leg shapes without forcing you back to the fitter, and the Power Spine metal plate linking cuff to shell means responsive, damp power transfer when you're driving the ski.

It weighs 1890 g per unit, making it light enough for a long day without feeling flimsy.

Who it's for

Intermediate skiers (ability 3) on all-mountain terrain who have a wider forefoot or full instep. The stiff flex suits skiers who want to feel the snow and make precise turns, and the generous last works for anyone who finds standard boots pinching at the metatarsal heads.

Fit and feel

A 102 mm last at Mondopoint 26.5 makes this one of the roomier options in Salomon's performance range. The shell and liner both heat-mould, so a bootfitter can open it up where you need space and keep it snug where you need control. The cuff is tall and well-padded; the three-position calf adjuster means you can dial in how tight it sits. The flex is stiff (120) but responsive, not brickish—you'll feel the snow and have good edge bite.

From the fitting room: Bring the boot and liner to your appointment cold. Heat-moulding takes 10 minutes and makes the difference between a good fit and a boot you'll actually want to wear all day.
