Adidas Energy BOOST: It looks like Styrofoam but it isn't

Adidas launched a new shoe with the name 'Energy Boost'. New in this shoe is the midsole. Where most midsoles are made of EVA (Ethyl Vinyl Acetate), with this shoe Adidas uses BOOST.


The midsole is made of TPU (Thermoplastic Polyurethane).

Solid granular material (TPU) is literally blown up and turned into thousands of small energy capsules which make up the footwear’s distinctive midsole.

With the cell structure, these capsules store and unleash energy more efficiently in every stride. Tests conducted by the Adidas Innovation Team show that the highly durable material found only in Energy Boost products provides the highest energy return in the running industry.

Additional benefits of this material is that its performance is more stable both over time and changing temperatures. Delivering a more constant ride to the runner.

Good marketing this about energy capsules but to me it looks like Styrofoam/polystyrene. Look at the picture. It looks like the sole was cut out of the protecting Styrofoam around your newly bought TV.

The video below illustrates the energy return.
