DUALFIT technology uses a special SBR material that is stretchable in four directions to produce liners for hard roller skate shoes. This allows one liner to fit two shoe sizes, providing a comfortable and precise fit and improving performance.

It involves allowing the shoe cuff to be adjusted in four positions. The cuff hinge is mounted in a special moulded pad, offering two options: a high or low cuff position.

It involves adapting the carbon fibre shell to the wearer's individual anatomy to optimise fit, comfort and performance.

UNIBODY consists of making the housing and frame as one single component. This design significantly reduces the need for additional mounting components, resulting in a reduction in weight. An additional advantage is the lowered centre of gravity, which provides better control and allows the use of larger wheels, maximising the benefits of this innovation.
