Manufacturing focused: the Boost midsole material is licensed by adidas from the BASF company. That means a licensing fee that makes the material more costly to use than if it had been developed in house (like Nike's React foam was).

At our adidas Factory Outlets we operate under the same adidas values that you'll find at our retail stores. We are inspired to see how our products positively impact people's lives on the playing fields and on the streets. Factory Outlets carry adidas product at a discount for our customers.

The Ultra BOOST has three key features that I love: the Primeknit upper, the torsion system, and boost energy foam. The Ultra BOOST is a really great daily trainer that could double as a race day pick as well. My next race is the Baltimore 10-miler in June and this shoe is certainly a contender.

The adidas Solar Boost is designed to replace the adidas Energy Boost, offering the same high-end Boost cushioning, but supported by new, cutting-edge technologies. With an almost full-length Boost midsole, this shoe stays true to the springy, responsive feel of the adidas Boost line.
