Power Starts Underfoot
In high-performance dinghy sailing, speed is built through connection. The sailor, boot, strap and boat work as one system, transferring force through every point of contact. When that system is locked in, the sailor can hike harder, hold a flatter boat and turn effort into success.
The Carbon X Insole has been developed for this exact load path. Engineered with Carbitex® Monoflex technology, it uses directional carbon fibre support to help sailors manage the extreme pressure placed through the foot during sustained hiking. It is flexible where natural movement is needed and stiff where the body needs support. It is targeted structure, placed underfoot to support one of the most demanding movements in dinghy sailing.
The Load Behind the Hike
Hiking places the foot under sustained load outside its natural movement pattern. As the sailor leans out from the side of the boat, body weight travels through the legs, into the boots and against the hiking strap. The feet become the primary connection point between sailor and boat, especially when paired with high-grip systems such as ZhikGrip™ II.
That grip creates leverage. More leverage helps the sailor drive force into the boat, but it also increases the pressure placed through the foot, ankle and lower leg. Under hard hiking load, the foot can be forced into extreme plantarflexion, where the toes are driven downward and the foot is pushed into a flattened position.
This position places strain across the top of the foot and through the ankle, with load continuing into the calves, shins, knees, hips and hip flexors. Over time, that pressure can accelerate fatigue and make it harder to maintain a strong, efficient hiking position.
The Carbon X Insole is designed to help manage this pressure at the point where it begins.
How Directional Carbon Support Works
Carbitex® Monoflex technology is a dynamic carbon fibre construction engineered to flex naturally with the foot in one direction while remaining stiff in the opposite direction. In the Carbon X Insole, that directional response is used to support the foot under hiking load without restricting natural movement around the boat.
The carbon fibre is laid up in a specific way. In one direction, it bends with the foot, allowing sailors to walk, move through manoeuvres and adjust position. In the opposite direction, it resists the force that pushes the forefoot down during hard hiking.
When the sailor hikes, the hiking strap drives load through the boot and across the foot. This can push the forefoot down into plantarflexion, placing pressure through the top of the foot and ankle. The Carbon X Insole acts against that downward bend, helping reduce forefoot collapse and creating a firmer base through the sole of the boot.
That firmer base supports a stronger leg position and helps improve how force transfers from the sailor into the strap. Instead of the foot absorbing and compensating for the load, the insole helps stabilise the platform beneath it.
In the opposite direction, the insole remains flexible. This means sailors can still move naturally across the boat, transition through manoeuvres and retain the connected feel required in elite dinghy sailing.
The result is targeted support where hiking creates the greatest strain, without unnecessary bulk or restriction.
Why It Matters for Performance
The benefit is the ability to sustain stronger output for longer. As dinghy footwear becomes more advanced, sailors can create more grip and more leverage against the boat. That is a performance advantage, but it also asks more from the body. With stronger connection comes greater force through the foot, ankle and lower leg.
The Carbon X Insole helps support that increased load. By resisting extreme plantarflexion, it reduces the demand placed on fatigued stabilising muscle groups and helps maintain a more efficient hiking position over time. For the sailor, that can mean holding form deeper into a race, applying pressure more consistently and reducing the breakdown in technique that comes with fatigue. Better support underfoot helps protect the connection between athlete and boat, keeping power directed where it matters.
Built for Zhik’s New Dinghy Boot Range
The Carbon X Insole is designed to work with Zhik’s new generation of dinghy footwear. It is made for the Hiking X Boot and is compatible with both X and Performance dinghy boots, giving sailors the ability to add directional carbon support across the range.
At just 60 grams, it delivers structure without unnecessary weight. Integrated cut-to-fit guides allow sailors to customise the fit across three size ranges, while the soft polyester lining adds comfort inside the boot. Paired with Zhik’s latest dinghy boots, the Carbon X Insole strengthens the full hiking system. Grip locks the sailor into the boat. Directional carbon support helps manage the load that follows.
Complete the Hiking System
Engineered From the Ground Up
The Carbon X Insole reflects Zhik’s approach to performance innovation: identify the pressure points athletes actually experience on the water, then engineer a precise solution around them.
By bringing directional carbon fibre support into the boot, it helps sailors manage the load of high-intensity hiking, reduce unnecessary strain and maintain power through longer, harder efforts. For sailors pushing the limits of grip, leverage and endurance, the Carbon X Insole adds targeted support where the hiking system needs it most.
