Product details
Chaya Onyx - Boot Only – Roller Derby Skate Boot
Chaya Onyx Boot Only is a roller derby skate boot without the chassis, designed for skaters who prefer full customization of their gear. With this option, you can choose any plate, trucks, and wheels, tailoring the skates to your riding style and individual preferences. The Onyx model offers incredible fit, maximum movement precision, and excellent foot support, ensuring full control in dynamic maneuvers and quick turns during a game.
Its low-profile construction provides greater freedom of movement without compromising foot and ankle support. The ultralight composite shell made from carbon fiber and Kevlar makes the boot extremely lightweight yet highly durable. MYFIT heat molding technology allows for precise boot customization to match the anatomical shape of the foot, enhancing comfort and control. The internal microfiber liner wraps around the foot for a snug fit, making the boot feel like a natural extension of the body, delivering exceptional movement precision.
The Chaya Onyx shell is designed for a perfect balance of fit and comfort, featuring a medium-width front and ankle area for stability and precise foot support. Flex cuts ensure better adaptability for skaters with wider feet, while a standard 7mm heel raise enhances energy transfer and agility, making the Onyx an excellent choice for roller derby.

About manufacturer

Chaya is nothing else than rollerskating division of renown inline skates manufacturer, Powerslide. It was created in collaboration with skaters from all over the world. From the very beginning of the project, it is overseen by Powerslide’s creative director, Kenneth Dedeu – he is not only a very talented designer and photographer, but also amazing skater and yes – rollerskater too (under nickname “Ragnaroll”). He wanted to forge Chaya in to very best rollerskating company out there and rounded up other amazing riders, too. Good examples are Barbara “Barbie” Luciana, the queen of Barcelona’s rollerskating scene (great vert and street skater too) and Kid Block, a talented roller derby player from Tiger Bay Brawlers team in Cardiff. A solid team provided invaluable feedback which helped creating innovative and high quality products.
Furthermore, all of that high end technology Powerslide is known for has found its way in to Chaya rollerskates. Carbon fibre shells, advanced composite materials, Recall foams, heat mouldable boots are just few examples. Street rollerskates are equipped with innovative, asymmetrical brindblock, the toe stopper placement in many models is offset for better power transfer on push, front of the baseplates is slightly curved upwards for better control – these are ideas that Chaya introduced to enhance rollerskating experience. Furthermore, no matter what is your style: dance, cruising, street and vert, roller derby – the brand have something for you in store!
