• Energy Return:
  The LEP torsion system combine with the iconic BOOST midsole to deliver superior energy return, 4% more than the Ultraboost 21 for women.
• LEP:
  The adidas Linear Energy Push is an evolution of the torsion system which works in harmony with the boost midsole and the newly designed outsole for a responsive ride.
• PRIMEKNIT+:
  The refined PRIMEKNIT+ forged zones are made with yarn containing 50% Parley Ocean Plastic, providing an adaptive fit.
• 360° fit improvement based on the female anatomy:
  The fit is based on a new last built on female anatomical insights. It reflects a narrower heel, a lower instep and keeps the unique S-curve heel.
