Designed around the foot.
Developed for the game.

Footwear fit cannot be defined by length alone. The human foot varies across several dimensions, including width, heel width and instep height, meaning that two feet of similar length can have meaningfully different shapes (Jurca et al., 2019).

This matters because the relationship between the foot and the boot influences how comfortably the foot can be accommodated. Incorrectly fitted footwear has been associated with foot pain and foot disorders, reinforcing the importance of considering overall foot geometry rather than relying on length alone (Buldt & Menz, 2018).

For a footballer, fit also forms part of the performance equation. The foot needs to remain appropriately supported while the player runs, changes direction and interacts with the ball and ground. Vincelux therefore starts with the shape of the foot. The relationship between the heel, midfoot, forefoot and toe box was considered as a connected structure rather than as independent measurements.

The aim was not simply to make the boot wider. It was to create appropriate space where the foot requires it while maintaining control through the rest of the boot.

The forefoot is one of the areas where footwear geometry can directly influence how pressure is distributed around the foot. Research has shown that toe-box shape and volume can alter forefoot interdigital and plantar pressures, demonstrating that the geometry of the front of the shoe matters (Branthwaite et al., 2013).

For Vincelux, this informed a more anatomical approach to the forefoot. The objective was not to create a loose boot, but to create useful space where the foot naturally needs it. That means accommodating the forefoot without abandoning the control required through the rest of the boot.

Toe-box dimensions may also influence movement performance. Research in athletic footwear has found that toe-box size can affect movement performance during cutting and lateral tasks (Zhang et al., 2025).

The result is a deliberate balance: enough space to better accommodate the forefoot, while maintaining the structure needed for football movement.

The upper is the primary material interface between the foot and the outside of the boot. Its properties therefore influence how the boot feels on the foot and how it behaves during football movements.

Vincelux uses a synthetic leather upper selected for softness, flexibility and controlled stretch, with the intention of allowing the material to adapt around different foot shapes while maintaining the structure required of a football boot.

Material selection is not purely a matter of comfort. Research examining football-boot materials has found differences in both kicking performance and perceived fit, indicating that the upper can influence how the player interacts with the boot and ball (Ahmad et al., 2015).

For Vincelux, the upper was therefore selected as part of the overall fit and interaction system: flexible enough to accommodate the foot, but controlled enough to maintain the structure required during play.

Accommodating the shape of the foot is only half of the fit equation. During football, the foot also needs to remain appropriately controlled inside the boot.

Vincelux therefore uses the heel and midfoot as key control zones. The heel lining uses microfibre to create a soft contact surface around the heel and help reduce unwanted movement, while the overall fit is designed to keep the foot appropriately positioned during movement.

The design objective is not maximum restriction. It is controlled movement: enough freedom for the foot to move naturally, with enough retention to prevent unnecessary movement between the foot and boot.

This becomes particularly important when accelerating, changing direction and transferring force through the foot. The boot therefore needs to accommodate the foot without allowing the foot to become unstable inside it.

Lateral lacing

The lacing system supports this approach by moving the adjustment area away from the central striking region while retaining the ability to adjust the fit.

The foot does not experience the sole as a single material. Vincelux uses a layered underfoot system in which different materials perform different roles.

Closest to the foot is TPE, selected for cushioning and elastic recovery. Beneath it is PEBA, a lightweight and resilient foam intended to contribute response. Below these layers sits the TPU outsole, which forms the structural base of the boot.

This layered approach allows the different requirements of the underfoot system to be considered separately rather than asking one material to perform every function.

Football-specific research has shown that insole and cleat configurations can influence plantar loading and perceived comfort during running and turning (Nunns et al., 2016). Research into sport-shoe cushioning has also examined the contribution of shock-absorbing foam materials to cushioning behaviour (Chiu & Shiang, 2007).

Everything above the outsole becomes relevant when force reaches the playing surface. The outsole therefore has to provide a combination of structure, stability and traction appropriate for football.

Vincelux uses TPU as the structural outsole material, selected for stability, durability and the demands of repeated football movement.

The soleplate is developed around modern 3G surfaces, with traction considered as a question of control rather than simply maximising grip. The objective is to provide the player with a predictable interaction with the surface while preserving the movement characteristics required during play.

This is important because more stiffness or more grip is not automatically better. Football research has shown that sole bending stiffness can alter game-specific physiological demands, demonstrating that sole construction can influence the way the player interacts with the boot and surface (Vienneau et al., 2016).

A football boot is an interaction between multiple components rather than a collection of independent features. Fit influences how the foot sits inside the boot. The forefoot determines how the front of the foot is accommodated. The upper forms the material interface. Heel and midfoot construction control movement within the boot. The underfoot system influences cushioning and response, while the outsole determines how the resulting forces interact with the playing surface.

That is why Vincelux was developed as a connected system.

The objective is not to maximise one characteristic at the expense of everything else. It is to find the appropriate balance between foot accommodation, comfort, control, movement and ground interaction.

The broader football-footwear literature recognises these same considerations as interconnected aspects of footwear design (Blanchard et al., 2018).

Published research informed many of the principles behind Vincelux, but research alone does not describe how a specific boot performs in the hands and feet of real players.

That is why Vincelux also uses its own player testing to evaluate the boot in real football contexts. Existing 9v9 testing has examined areas including comfort, lockdown, natural movement, pressure points, change of direction and match use. These findings represent Vincelux testing, rather than independent scientific research.

The distinction is important.

Published research helps establish the scientific context. Vincelux testing helps us understand how our own design behaves in practice.

Together, they create a development process in which the boot is informed by evidence, built into a physical product and then evaluated on the pitch.
