The all-day shoe with dual-density Helion™ to make the city dance to your rhythm. We have re-engineered the bottom unit from scratch. Our goal? Even better cushioning and a smooth forward-rolling sensation. Our solution? A new dual-density CloudTec® midsole from Helion™ superfoam. Adding to that: a Speedboard® that repurposes the saved energy from landing into powerful take-offs.
