Produktbeschreibung

The Helu Aera Carbon is hezos high-performance road cycling shoe developed by HEZO in collaboration with the amateur cycling team *Kern-Haus*. It was designed specifically to meet the demands of stage races, where efficiency, comfort and durability must be maintained over long periods and varying conditions. The model will be presented and launched for the first time at Cyclingworld.
A key focus of the Helu Aera Carbon lies in the use of specialized, bio-based performance polymers.
The sole structure is made from PA11 carbon combined with Pebax®, PA11 derived from castor oil. These materials were chosen for their favorable balance between stiffness, flexibility and rebound behavior, as well as their comparatively low material density of 0.87 g/cm³.
Due to this material choice and optimized structural design, the Helu Aera Carbon is approximately 20% lighter than HEZO’s standard road model, while maintaining the required stiffness for efficient power transfer. The use of bio-based polymers also contributes to a reduced environmental impact compared to conventional petroleum-based materials.
Digital Customization Process

Like all HEZO shoes, the Helu Aera Carbon is custom-made. The fitting process is based on a smartphone foot scan performed at home. Using three photographs of the foot taken with a DIN A4 reference sheet, HEZO’s software generates a digital foot model that serves as the basis for the individualized shoe geometry.

Every part of the shoe is 3D printed separately, using different materials exactly where they make sense. Stiff where you need power, flexible and soft where you need comfort.
We don’t use glue. All components are mechanically connected, so they can be easily separated and recycled by material type. That’s better for performance, easier to repair, and the right move for sustainability.

This process allows HEZO to produce each shoe according to the anatomical requirements of the rider, rather than adapting the rider to a predefined standard size.
Development and Production Context

HEZO was founded in 2022 and develops its products entirely in-house. This includes the design and engineering of the shoes, the development of the scanning and fitting software, and the setup of its own production facility.The founding team consists of Carsten (mechanical engineering), Helen (product design) and Nils (computer science, PhD). The interdisciplinary background of the team enables a close integration of material research, digital processes and product development.
