SWIFTFOAM™ MIDSOLE
A Low Carbon Runner’s High
How do you make a running shoe that’s super springy, responsive and super sustainable? It starts at the midsole. To create our SwiftFoam™ midsole, we use a first-of-its kind, one step foaming process that makes this the lowest energy midsole production process on the market, with a compound that delivers a finished part with 48% bio content.

RE-ENGINEERED UPPER
Secure For Every Stride
We reimagined the eucalyptus tree upper with a zonal knit– aka more stretch across the top and toes for breathability, and a tighter knit in the midfoot to help lock the foot into place.

INCREASED TRACTION
Go Further With Extra Grip
Made with an updated natural rubber compound, the horizontal lug pattern (designed perpendicular to your running motion) helps grip the road with more traction, even in wet or rainy weather.

Good travel shoes but snug.
They're good travel shoes but can be a bit snug if worn for a long time.
