The Midlength Mk II marks the next step forward in Armstrong’s board design, debuting our all-new molded board technology. Built to deliver a lighter, stronger, and more connected ride, it represents a major leap in durability, response, and long-term performance.

Refined through years of testing in New Zealand’s most demanding conditions, the Midlength Mk II 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 around Armstrong’s new X-Form Precision Molded Board Technology, the Midlength Mk II 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.

On the water, the Midlength Mk II feels composed, responsive, and predictable. The thinner X-Form profile delivers a more direct connection to the foil while the refined bottom design reduces sticking and tracking for cleaner touchdowns and faster recovery.
Combined with a surf-style squash tail, Forward Geometry foil track, integrated carbon foil tracks, dual carbon stringer system, and redesigned deck grip, the Midlength Mk II delivers greater control, confidence, and progression across all foiling disciplines.

Ideal for:
Winging
Parawinging

Construction:
X-Form – Precision Molded Board Technology

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 we envisioned, we didn’t compromise, we built our 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.

Why we built X-Form?
Optimal Strength to Weight Ratio.
X-Form was developed to reduce weight while solving long-standing durability and consistency challenges, this construction delivers an uncompromising strength to weight
