NEW YORK—Two years after the company introduced the Boost cushioning system to the world, adidas introduced what it claims to be its most technically-advanced running shoe, Ultra Boost, at a media event in New York Thursday that featured the likes of sprinter Yohan Blake, pole vaulter Jenn Suhr, and marathoner Wilson Kipsang.

The new Ultra Boost features 3000 energy capsules of thermoplastic polyurethane (TPU) in the midsole, about 20 percent more than any shoe along with a Primeknit upper to provide a precision fit & maximum breathability, while the midsole returns energy with each step.

Ultra Boost also features an entirely new heel construction that frees the natural movement of the Achilles tendon. A carefully tuned external heel counter comfortably cradles the foot and adapts to the high extension of the Achilles. A new featherweight sock liner adapts to the runner's natural foot form, for a customized fit and feel. 

Ultra Boost also boasts a new dual-density torsion system embedded into the shoe's base. This allows more independent movement between heel and forefoot for superior stability and a smooth, more controlled run.

The shoe releases to the public on February 11th with a MSRP of $180.00.
