Salomon S/Pro Delta S BOA 120 Ski Boots 2027

Bootfitter's Notes

The S/Pro Delta 120 is an all-new platform for Salomon, designed specifically for skiers who need more room without stepping into an overly soft or imprecise boot. Built around the new Delta shell, it offers a true high-volume fit that feels balanced rather than oversized.

The heel pocket has excellent retention for a high-volume boot, while the midfoot, forefoot, and instep provide noticeably more room than Salomon's S/Pro Alpha or Supra families. It's a boot with real substance—it doesn't feel like a cavern—but it accommodates higher-volume feet exceptionally well.

Compared to Salomon's previous high-volume offerings, the Delta also improves calf fit. The cuff is noticeably more forgiving and works well with a much wider range of calf shapes and sizes, making it a great option for skiers who often feel squeezed around the lower leg.

The shell uses a softer instep material that makes getting the boot on and off surprisingly easy, while both the shell and liner are fully heat moldable for straightforward customization if needed.

On snow, the 120 flex is powerful without feeling punishing. It has enough support to confidently drive modern all-mountain skis through chopped-up snow, steeps, and firm groomers, but the flex remains smooth and progressive rather than abrupt. Power transfer is direct, the rebound is energetic, and the boot maintains a predictable feel that encourages confident skiing all day long.

For intermediate through expert skiers who want a high-volume boot that prioritizes comfort without sacrificing performance, the S/Pro Delta 120 is one of the strongest new additions to the category. It delivers a roomy fit, excellent heel hold, and the kind of balanced flex that makes every run easier and more enjoyable.
