Boston, Massachusetts; August 4, 2020 — Global sports brand PUMA, as part of a sponsored research collaboration with MIT Design Lab, has created XETIC, a cushioning technology, which will start a new era by combining the worlds of mechanical cushioning and foam. This ultramodern performance innovation will provide for an excellent comfort for walking and will be first introduced in a new street-ready sneaker called Calibrate Runner. 
While the futuristic visible technology of XETIC may look like 3D printing at first, XETIC is not made of plastic, it is foam. XETIC takes its name from “auxetic materials”, structures, which behave in a certain way when they are subjected to mechanical stresses such as compression. 
For XETIC, this means the cushioning provides an excellent comfort for all wearing occasions. “PUMA’s innovation department teamed up with MIT Design Lab because we needed their high-expert engineering capabilities,” said Romain Girard, Senior Head of Innovation at PUMA. “MIT has computer simulation possibilities, which enabled us to see the behavior of the material and quickly find the optimal structure for calculated cushioning.” 
 PUMA and MIT Design Lab worked with an extensive runner community to analyze individual running specifics, such as pressure points, and they then took the data to develop a specifically shaped structure that allows for progressive cushioning. The result was a structure shaped like the horizontal number 8, which is characteristic for the XETIC. The whole team was delighted with the ability to work on a project that allowed them to explore such a new space and to see all the efforts culminating in the creation of the Calibrate Runner. Over the course of the project qualitative and quantitative user testing was used, a novel finite element analysis simulation, and parametric design to find the perfect pattern, which was named ‘Recurve’.
