What is the difference between Dual BOA and single BOA?

Dual BOA has two independent dials — one for the upper cuff (shin/calf wrap) and one for the lower shell (forefoot wrap). Single BOA has only one dial on the lower shell. Dual BOA gives you more precise, zone-specific fit control.

What does the 6mm back spoiler do?

The spoiler inserts between the top of the cuff and the liner to add forward lean. More forward lean means more engagement into the front of the boot, which aggressive skiers prefer for immediate edge response.

How does Custom Shell HD work?

A bootfitter heats specific areas of the lower shell and expands them with a press. The thin-wall construction and specialized materials allow the foot to sit closer to the shell for better feel, while creating room exactly where you need it. Takes about 10 minutes.

Description

The S/PRO SUPRA DUAL BOA 130 is Salomon's first dual-dial BOA alpine boot, built on their 100mm Supra last — a medium-volume shell that fits a broad range of foot shapes and can be heat-molded via Custom Shell HD to push closer to 106mm for wider feet. The 130 flex is legitimately stiff: it demands a strong, forward-driving skier to work properly, and in return it delivers immediate, damp edge response with very little wasted movement between your leg and the ski. Instead of two upper buckles, a dedicated cuff BOA dial wraps the lower leg with cable tension that runs evenly around the shaft — no pressure point, no gap — while the lower dial manages the forefoot and instep independently. The My Exowrap 4D Race liner heat-molds alongside the shell, so the boot can be custom-fit as a complete system rather than two separate parts. GripWalk soles come standard, which helps on hard lodge floors and parking lots, though this is a downhill-only boot: there is no walk or hike mode.

This boot makes sense for expert men's skiers who spend their days on groomed terrain and harder snow, ski with a strong, deliberate stance, and have a medium-width foot in the 99–101mm range. If your foot is genuinely low-volume or narrow, the single-BOA S/Pro Supra BOA 130 — with its slightly different fit geometry — may seal better around the heel before heat-molding. If 130 flex is more than your legs can consistently drive, the SUPRA DUAL BOA 120 is the direct step-down in this same platform and closure system, and it will reward an advanced skier without punishing them for a slightly softer technique. Wide or high-volume feet that don't respond to the Custom Shell HD process belong in a different shell entirely — come in for a fitting, because forcing a 100mm last onto a 104mm foot leads to pain and lost control, not performance. Flex and last width have to match the foot and the skier, and that is the only way this boot does what it promises.

The S/PRO Supra Dual BOA 130 is the top of Salomon's piste boot lineup — two BOA dials replace traditional buckle adjustments on both the upper cuff and lower shell. The upper dial wraps the calf and shin; the lower dial wraps the forefoot. Together, they provide the most even, micro-adjustable pressure distribution you can get in an alpine boot. The ExoWrap construction with Powerspine technology delivers aggressive power transmission, and the Custom Shell HD lets a bootfitter personalize the lower shell in 10 minutes.

At $623, this is a serious investment. You're paying for dual BOA, ExoWrap construction, and a premium 4D liner. The 6mm back spoiler in the box adds forward lean for extra engagement. For expert skiers who demand both performance and convenience, this is the boot that does it all without compromise.

Strengths

+Dual BOA dials — independent upper and lower fit adjustment, micro-tunable with gloves
+ExoWrap + Powerspine construction for top-tier power transmission
+Custom Shell HD allows rapid bootfitter personalization of the lower shell

Best For

Expert medium-volume skiers who want the ultimate in on-piste performance with dual BOA convenience.

Limitations

−Premium $623 price — the most expensive boot in the S/PRO lineup
−Two BOA cables means two potential failure points (rare but possible)
−Flex 130 is very stiff — lighter skiers or less aggressive experts should consider the 120

Not For

Budget buyers, lighter skiers (120 flex is more appropriate), wide-footed skiers (100mm last), or touring-focused skiers.
