From "unicorn foam" to rubber-free soles

The collaboration between Dow and Under Armour resulted in the UA Flow technology, known as the "Unicorn Foam." This material achieved the industry's first rubberless outsole "unitsole" design, significantly reducing weight while enhancing grip and durability.

The foam material formula provided by Dow balances high energy return, cushioning, and durability, helping athletes achieve faster speeds and greater stability on the basketball court. This innovation has been applied to top basketball shoes like the Curry Flow 8 and has received recognition with the 2022 Edison Award.

Dow Performance Footwear's technological roadmap showcases the future direction of the footwear industry, where the pursuit of ultimate performance goes hand in hand with environmental responsibility.
