Support Guide
Neutral
Brooks shoes that are designated “neutral” are designed to deliver comfort and durability for a neutral stride — one that doesn’t need additional support.
Support
Brooks shoes with the “GTS” designation feature our Go-To-Support, which helps keep runners in their natural stride, even when they tire. Think of bumpers in a bowling lane!
Maximum Support
To provide maximum support, we pair our go-to-support (GTS) with additional features such as an extra wide base to enhance stability.
