Armstrong Mid-Length MkII X-Form Foil Board

Armstrong Midlength Mk II

The Armstrong Midlength Mk II represents the next evolution in foil board design, combining exceptional efficiency, refined control, and cutting-edge construction technology to create one of the most versatile and capable boards in the modern foiling market. Developed through extensive testing in New Zealand's demanding coastal conditions, the Midlength Mk II delivers effortless glide, rapid take-offs, and outstanding stability while maintaining the responsive handling that advanced riders demand.

At the heart of the Midlength Mk II is Armstrong's revolutionary X-Form construction. This precision-moulded technology has been engineered to maximise the strength-to-weight ratio, producing a board that is lighter, stiffer, and more durable than traditional constructions. The result is a remarkably direct connection between rider and foil, delivering immediate feedback and a highly responsive feel underfoot. Designed to maintain its performance season after season, the X-Form platform offers exceptional durability without compromising weight or ride quality.

The all-new shape has been completely refined to enhance every aspect of foiling performance. A thinner overall profile reduces swing weight and improves board-to-foil connection, while carefully optimised volume distribution creates impressive stability for its size. The longer, narrower outline promotes efficient acceleration and glide, allowing riders to generate speed with less effort and achieve earlier take-offs in lighter conditions. Whether wing foiling, prone foiling, downwind foiling or utilising foil assist systems, the Midlength Mk II excels across a broad range of disciplines.

A redesigned bottom shape minimises sticking and tracking during touchdowns, enabling smoother recoveries and maintaining momentum when conditions become challenging. The surf-inspired squash tail increases planing efficiency and improves release from the water, helping riders accelerate onto foil quickly while enhancing overall stability during take-off. Combined with Armstrong's Forward Geometry foil track positioning, the board delivers a balanced, manoeuvrable ride with a more centralised feel beneath the rider.

On deck, the Midlength Mk II has been carefully configured for maximum rider comfort and control. The redesigned deck grip provides excellent traction while reducing overall weight, and integrated deck references including a raised arch bar, wedge system, and foil track indicators help riders consistently position their feet for optimal performance. Multiple footstrap insert options allow for complete setup customisation, whether pursuing freeride efficiency, high-speed carving, wave riding, or advanced aerial manoeuvres.

Available in a wide range of volumes from compact high-performance sizes through to larger light-wind and progression-oriented models, the Midlength Mk II offers a solution for riders across all skill levels. Smaller sizes provide a highly agile and responsive ride for experienced foilers, while larger models deliver exceptional efficiency, easy take-offs, and increased stability for riders looking to maximise time on foil in marginal conditions.

The Armstrong Midlength Mk II is more than just an update—it is a complete reimagining of the modern foil board. Combining advanced construction, refined shaping, and exceptional versatility, it delivers effortless efficiency, intuitive control, and a uniquely connected riding experience that sets a new benchmark for performance foiling.
