ARMSTRONG MIDLENGTH X-FORM MKII Foil Board

Refined through years of testing in New Zealand’s most demanding conditions, the Midlength Mk ll blends Armstrong’s signature feel with a new level of control and consistency. It’s designed not just to perform, but to keep performing session after session.

BUILT TO LAST

From the beginning, Armstrong was built on a simple belief: riders should be able to trust their equipment in the harshest conditions, every day. X-Form was born from that same mindset. When existing manufacturing methods couldn’t deliver the strength, precision, and durability they envisioned, and didn’t compromise, and built their own purpose designed factory. X-Form represents our commitment to doing things properly, using precision manufacturing to create boards that are stronger, more consistent, and built to progress with riders over time.

OPTIMAL STRENGTH TO WEIGHT

The new Armstrong X-Form precision molded board technology was developed to reduce weight while solving long-standing durability and consistency challenges, this construction delivers an uncompromising strength to weight ratio with precision-tuned performance. Stronger, stiffer, and more durable than traditional constructions, it maintains the connected feel Armstrong boards are known for while eliminating softening and fatigue over time.

EXACT FORM, EVERY TIME.

X-Form is created with Armstrong’s industry leading proprietary CNC-machined molds that locks every component into place simultaneously. It is formed in one cycle, under uniform pressure and temperature, with zero distortion. Drawing on Armstrong’s deep experience designing and manufacturing CNC-machined molds and high-precision molded foils, this process brings proven industrial accuracy to board construction.

HIGH DENSITY PVC WRAP

Entire internal surface of board wrapped in high density PVC – even if it does crack it won’t absorb water like EPS foam would.

ULTRALIGHT LARGE SPHERE EPS CORE

The high pressure molded layup is super stiff and the ultralight eps core absorbs shocks for solid and smooth ride no matter what psycho moves you pull. Explore your inner Cash

HIGH DENSITY PVC RAILS

High density PVC foam wrap of the whole perimeter of board. Protect the areas of the board most at risk to damage.

FOIL ASSIST COMPATIBLE

Foil Assist compatible window for clean, uninterrupted remote signal.

DUAL CARBON STRINGER SYSTEM = Maximum Rigidity

Armstrong’s reputed i-beam top to bottom dual carbon stringers provides maximum structural rigidity and durability by fully connecting the deck and bottom of the board.

COMPOSED. RESPONSIVE. PREDICTABLE.

On the water, the Midlength Mk Il feels composed, responsive, and predictable. The improved stiffness profile creates a clean, connected sensation underfoot, allowing riders to feel exactly what the foil is doing.

The result is more confidence at speed, better control in critical moments, and a smoother, more intuitive riding experience across disciplines.

MORE DIRECT CONNECTION

Thanks to the new X-Form construction the refined profile features a considerably thinner board, delivering a more direct connection to the foil and reducing unwanted touch-downs. Optimised volume distribution maintains stability and balance while allowing the board to sit lower to the water, creating a cleaner, more responsive feel underfoot. The result is a thinner, more connected board that enhances control, feedback, and confidence across all conditions.

REDUCED STICKING & TRACKING

The new bottom design is shaped to optimize fluid dynamics at every phase of flight. A refined double concave transitioning to a subtle V helps generate early lift, making takeoffs easier and more efficient while smoothing touch-downs. When the board reconnects with the water, it glances off the surface rather than sticking or tracking, allowing for quick, clean release back onto foil. Shallower chines and a flatter bottom through the rear further reduce drag and resistance, creating a fast, predictable feel that supports takeoffs and landings.

SURF STYLE SQUASH TAIL

The surf-style squashed tail adds stability when getting onto the board, making early positioning and balance more intuitive. By allowing the rails to remain more parallel for longer, the shape increases surface efficiency and helps generate speed quickly, improving takeoff performance.

The result is a tail design that feels stable underfoot while delivering faster, more confident launches onto foil.

FORWARD GEOMETRY FOIL TRACK

Armstrong’s Forward Geometry concept, introduced in 2021, redefined foilboard design by placing the foil more centrally to reduce swing weight and increase responsiveness, while remaining compatible with any foil system. The MidLength Mk ll continues this legacy with FG foil tracks positioned further forward for enhanced maneuverability and a more connected feel on foil across all board sizes.

MORE GRIP, MORE CONTROL

The new Midlength Mk ll board is all about fun and progression whether you’re just figuring out parawinging or pushing the limits of carving style in short period skatepark conditions. A new deck grip designed to reduce weight and add grip.
