GO Cirrus R100
Meet the GO Cirrus R100, the lightest addition to our VIP lineup. Inspired by zero-gravity engineering, the Cirrus is designed for those who demand all-day comfort without the weight. The ultra-breathable "Ghost Mesh" upper adapts to the natural shape of your foot, while the Cloud-Form™ midsole absorbs impact to deliver a sensation closer to floating than running. With its clean, monochromatic aesthetic, it transitions seamlessly from a morning recovery run to a busy day in the city.
Exclusive VIP Access
The GO Cirrus R100 is a limited-release silhouette available only to GO Running VIP members.
