Care Guide

Remove the laces and insoles.
Place shoes in a delicates bag (pro tip: a pillowcase works too).
Choose a gentle cycle with cold water & mild detergent.
Shake out any excess water & set aside to air dry.
Shoes will regain their original shape with one or two wears.
For a full refresh experience, swap in a new insole and laces.

Handy tips: Don’t put them in the dryer. They’ll go back to their original shape in no time. You can hand wash your laces and insoles on their own.

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.
