Appleslice V4: The next evolution of our most versatile wing board
Wing foiling is evolving faster than ever, and so are we.
The AppleSlice V4 is a refined version of our best-selling wing board, redesigned to deliver next-level precision, control, and connection.
Building on the proven performance of the V3, this new shape feels smoother, lighter, and more balanced underfoot. While keeping the same all-around versatility that made the Slice a favourite for riders everywhere.
Whether you’re progressing from intermediate to advanced, or looking for a high-performance sinker for carving and freestyle, the AppleSlice V4 is built to keep you evolving.
The new design
The V4 introduces updates that you’ll feel from the first session.
A narrower outline on the mid-range sizes gives the board a faster, more agile feel. Perfect for riders looking for extra precision and responsiveness. The 70L size now sits perfectly between sinker and mid-size boards, offering the best of both worlds.
The tail has been refined too: a narrower back section releases water more cleanly, giving smoother flow and improved control in carving turns. The result is a board that feels more efficient through the water.
We’ve also shifted the wide point slightly forward to create more lift under the front foot. This makes early take-off easier and gives the board a naturally balanced glide. Especially noticeable in smaller, performance-oriented volumes.
A slightly increased nose rocker helps the board get onto foil faster and makes it more forgiving when accelerating or cutting through chop, giving you softer, smoother, and more predictable touchdowns.
The new concave deck under the front foot locks you in, enhancing grip and connection with the foil. It provides clear feedback without sacrificing comfort, while the extra front-end volume adds stability when you need it most.
All these updates come together to make the Appleslice V4 feel more reactive, controlled, and confident. A true evolution of the design!
Refined setup
The updated insert configuration keeps the board lighter overall. The new deck pad layout now extends further toward the tail and lies flatter, offering a smoother setup and better protection during transport.
Who it’s for
Whether you’re stepping up from the first board or chasing a high-performance sinker, the AppleSlice V4 adapts to your progression.
It’s intuitive for intermediate riders and finely tuned for advanced foilers who want that blend of precision, speed, and flow that makes every session feel alive.
Choosing Your Size
The AppleSlice V4 comes in a wide range of volumes to suit every riding style:
- Smaller sizes (50 L–60 L) – Designed for advanced riders who want maximum reactivity, control, and direct feel.
- Mid sizes (70 L–80 L) – The perfect blend of performance and accessibility for intermediate to advanced riders.
- Larger sizes (90 L–115 L) – Offer great stability, smooth early lift, and confidence for progressing riders or light-wind sessions.
FOIL CONSTRUCTION
50K CLOSED CELL FOAM
It all starts with the core and every board we make starts with a foam core of our very own 50K closed cell foam. This foam is formalized exclusively for us, it is not used in any other board in the market.
The foam can withstand 50.000 kg per square meter, while staying very light, and most of all very flexible. Another plus of our 50K foam is that it is closed cell, meaning that the foam will not take in water, and the board will not blow out when it gets hot.
100% CARBON FIBER CONSTRUCTION
All our foil boards are produced in our 100% carbon fiber construction. You want carbon fiber in a foil board for its stiffness and strength. A stiff board will give you the best control and response from the foil. Also stiffness will make pumping the foil much more effective. With carbon fiber we are able to make the board extremely strong while really light at the same time.
The most stress in a foil board is in the connection of the foil to the board. So this is where we put extra care and attention to make it the strongest connection available. The foil mount is CNC cut with the board, for the highest precision. We only use FUTURES oneshot boxes as they are the strongest in the industry. The boxes are placed in a panel of ultra high density PET honeycomb. This PET honeycomb itself is sandwiched in carbon again. Meaning there is carbon fiber both inside the board and outside. The honeycombs open structure ensures a solid connection between inside and outside, fusing everything together into a solid block.
Our lamination is completely different as well. We use a vacuum technique developed in house, where we layer all the carbon fiber, and reinforcements on the board dry. Then we extract all the air from the bag and inject the epoxy resin under pressure. This results in the tightest lamination possible, with the best ration between fiber and epoxy. It also gives 100% connection to the core so the boards do not delaminate. Extra patches under the feet prevent heel denting.
Inserts in our foil range are made from blocks of high density material. And can be customized position wise. These blocks are also fused to the core so they never pull out.
