FLOW ACE or INFINITY ACE? Which Foil Is Right for You?

Choosing a new foil can feel complicated. Front wing size, aspect ratio, glide, speed, lift and carving all matter, but the most important question is much simpler: How do you want your foil to feel, and where do you want to use it?

The ENSIS FLOW ACE and ENSIS INFINITY ACE are both high-end carbon foils for intermediate to expert riders. Both are efficient, agile and built around the direct feel of the advanced MANIAC Monobloc System. However, they create two distinct riding experiences.

The INFINITY ACE is the more versatile all-round foil. It offers a stable yet agile and fast ride, covering everything from freeride and freestyle to wave riding.

The FLOW ACE puts more focus on glide, pumping efficiency and low-end performance for its size. It is ideal for swell-oriented riding, connecting bumps and making the most out of lighter-wind sessions.

What They Share

Both foils belong to the ENSIS ACE range and feature the advanced MANIAC Monobloc System, which seamlessly integrates the front wing and stabilizer with their respective fuselages into dedicated one-piece carbon components. By eliminating two connection points, the system reduces flex while increasing overall stiffness and efficiency. Both foil sets are a testament to meticulous engineering: lightweight, high-performing, and fully compatible with all MANIAC masts.

Both foils are designed for riders who have moved beyond their first flights and want a foil that offers room to progress.

The Fast and Dynamic Feeling – INFINITY ACE

The INFINITY ACE is the action-packed option. Its mid-to-high aspect design combines speed, agility, lift and control with explosive pop. It accelerates quickly, reacts directly to rider input and carries speed through sharp turns.

This makes it the natural choice for wing foilers who enjoy high-energy freeriding, freestyle, fast wave riding or racing with friends. If you want to boost jumps, work on tricks or carve aggressively, the INFINITY ACE delivers the responsive feeling and stable landings that help you push harder.

The range extends from 540 to 1390 cm², so the character changes with the size. The smaller sizes prioritise speed, tight carving and pop for experienced riders. The middle sizes balance performance and versatility for freeride, waves and freestyle. The larger sizes add lift and low-speed support for light-wind wing foiling, parawinging and downwind use while keeping the playful INFINITY ACE feel.

Choose the INFINITY ACE if wing foiling is your main sport and you want your foil to feel fast, lively and reactive.

The Glide and Flow Feeling – FLOW ACE

The FLOW ACE takes a different approach. Its high-aspect outline and exceptionally slim profile reduce drag and help the foil carry speed with minimal effort. Dependable low-end lift keeps it flying through slower sections, while the tapered wingtips and refined outline make it intuitive and controlled in turns.

This is the foil for riders who want to stay with the swell, connect one section to the next and spend less energy maintaining flight. It remains playful and carves smoothly, but its defining qualities are glide and efficiency rather than explosive pop.

That makes the FLOW ACE especially suited to downwinding, parawinging, prone foiling and SUP foiling. Wing foilers who prioritise waves, long gliding turns and efficient freeriding will also feel at home on it. For pump foiling, the bigger sizes offer plenty of lift, easy pumping and an efficient option for riders who want to use the same foil across several sports.

Choose the FLOW ACE for exceptional glide, pumping efficiency, strong low-end performance and mixing several foil disciplines, with a focus on waves and swell.

Which Size Should You Choose?

First choose the foil character that matches your riding. Then select the size according to your sport, body weight, conditions and experience.

FLOW ACE sizes

720: For wing, parawing and prone foiling. The fastest FLOW ACE, with outstanding glide and sharp carving for moving quickly between swells.
900: For wing, parawing, prone and pump foiling. A highly versatile size with a strong balance of lift, glide and carving – the do-it-all option in the FLOW ACE range.
1080: For prone, SUP, wing, parawingand pump foiling. Earlier lift for catching smaller bumps while remaining fast and efficient enough to link multiple swells.
1260: For prone, SUP, parawing, wing and pump foiling. Plenty of lift, easy pumping and a strong choice for light wind, beginner SUP downwinders and riders who value longer glide with less fatigue.

INFINITY ACE sizes

540 and 690: For experienced riders who prioritise maximum speed, fast carving, freestyle, racing and strong-wind wing or kite foiling.
840 and 990: Versatile wing foil sizes for freeride, waves and freestyle, with the 990 adding more lift and glide for moderate conditions and selected parawing or prone use.
1140 and 1390: For more lift, easier low-speed flight, light-wind wing foiling and heavier riders. They are also strong options for parawing and downwind riders.

Which One Is Right for You?

Choose the INFINITY ACE if you:

mainly wing foil;
want maximum speed, pop and direct reactions;
enjoy freestyle, jumps, fast freeriding or aggressive carving;
prefer a lively, high-energy ride.

Choose the FLOW ACE if you:

prioritise glide, pump efficiency and easy speed retention;
ride waves or swell and want to connect turns and bumps;
downwind, parawing, prone foil or SUP and Pump foil;
want one foil for several wave- and swell-driven disciplines;
want an efficient multi-sport option that also works for pump foiling.

Neither foil replaces the other. The INFINITY ACE rewards an active rider who wants speed, pop and immediate response. The FLOW ACE rewards a rider who wants to glide farther, connect more and use less energy along the way.

Once you know which of those experiences matters most to you, the choice becomes simple.
