Programmed cushioning
Xetic technology began with the exploration of metamaterials and the use of auxetic patterning as a means for bringing cushioning to running shoes. The name Xetic, pronounced ze-tik, is derived from the word auxetic, a structure that has a negative Poisson ratio forcing it to deform in a prescribed manner when stretched.
Real design in the virtual world
State-of-the-art methodology was used to design and characterise the performance of auxetic patterns and to build a simulation engine for predicting and improving pattern performance without physical iteration.
Iterate, experiment and optimise
A full exploration of multiple auxetic patterns were created computationally and evaluated using finite element analysis (FEA).
Computational parametric design
Once the optimal auxetic pattern was defined, generative design software was used to place the pattern based on specific localised requirements.
High definition digital simulation
Performance of the complete midsole design was simulated, visualised and measured allowing for fast iterative refinement and further optimisation.
Design for manufacture
This visualises the forces applied to the midsole while running in the context of the production mold. Here the injection molding pins that form the auxetic pattern are also shown.
A technology platform is born
Three years in the making, Xetic technology is the result of clear vision, elite talent and committed collaboration.
Research partnership
Xetic is one of the innovations that emerged from a three year partnership with the MIT Design Lab that focused on Adaptive Dynamic sports technology innovation. The elite, multidisciplinary team of engineers, software developers, architects and designers produced volumes of research, data and solutions that formed the foundation of a one-of-a-kind technology platform. Metaride Midsole was the working name for the project.
Project Profile
What is it?
A new and unique performance footwear technology that combines foam cushioning with mechanical cushioning.
Why is it innovative?
Xetic was engineered using state-of-the-art generative design software. It allowed for the creation of a totally unique looking and functionally superior product architecture. The software allowed us to iterate numerous designs quickly and simulate them virtually saving us both the time and cost of building the product in reality.
What were the biggest challenges?
Designing the production molds for this non-traditional and complex shape as well as refining a foam compound that did not produce air bubbles during manufacturing.
What was your role? Technology Enabler, Collaboration Leader, Chief Evangelist
Xetic technology emerged from the partnership between Puma Innovation and the MIT Design Lab. I set the vision and challenged the team at MIT to engineer the structure and validate it using digital simulation.
Why was it successful?
We proved a new product development methodology and successfully brought the patented technology to market.
