Armstrong Midlength Mk II X-Form Foil Board 2026

Designed For The Next Era Of Foiling

The new Armstrong Midlength Mk II X-Form isn't simply an update—it's a complete rethink of how high-performance foil boards are built.

Introducing X-Form Precision Molded Board Technology, Armstrong's most advanced board construction to date. Developed in Armstrong's purpose-built manufacturing facility and refined through years of testing in New Zealand's harshest conditions, X-Form delivers a board that is lighter, stronger, stiffer and more durable than traditional constructions.

The result is a board that feels incredibly connected underfoot from day one—and continues to feel that way season after season.

Whether you're winging in marginal winds, chasing swell with a parawing or looking for the ultimate all-round progression platform, the Midlength Mk II offers effortless efficiency, intuitive stability and confidence-inspiring control.

Why Riders Love The Midlength Mk II

Fly Earlier. Ride Longer.

The Midlength concept has become one of the most popular board categories in modern foiling for one simple reason:

It gets you on foil easier.

The longer waterline creates exceptional glide and acceleration, allowing riders to generate speed efficiently and lift onto foil with less effort. Once flying, the board feels compact, responsive and highly manoeuvrable thanks to Armstrong's Forward Geometry design.

A More Connected Ride

X-Form construction allows Armstrong to create a significantly thinner board profile without sacrificing strength.

That means:

✓ Better foil feedback

✓ Improved board control

✓ More precise foot pressure

✓ Faster progression

✓ Greater confidence at speed

The connection between rider and foil feels immediate, intuitive and incredibly precise.

Built To Last

Traditional board constructions gradually soften and lose their original ride characteristics.

X-Form was designed specifically to eliminate this problem.

With a precision-molded structure, full PVC reinforcement, carbon foil tracks and Armstrong's renowned Dual Carbon Stringer System, the Midlength Mk II is engineered to maintain its stiffness and performance for years of hard use.

Because progression happens faster when your equipment performs exactly as intended.
