A refined version of the UltraBoost 19
After we got a preview a few months ago, adidas officially unveiled the UltraBoost 20. Despite having a similar build with the UltraBoost 19, adidas made several tweaks to the 2020 model. These include an updated Primeknit upper with a new feature called Tailored Fiber Placement, where Primeknit fibers are tuned down to the millimeter for a better fit.
The Boost midsole retains the Torsion system, while the Continental rubber outsole gets Stretchweb for better heel-to-toe transition.
For its debut colorways, adidas partnered with the International Space Station, where you get iridescent Boost midsoles, along with the ISS’ logo on the tongue.
All three pairs are slated to drop on December 6.
