The Adrenaline is the go-to shoe for thousands and thousands of runners. So you shouldn’t be shocked to find out that Brooks took it easy in the updates department when it came time to revamp the Adrenaline GTS 12. After all, why mess with such a good thing?
The midsole of the 12 carries over, but the upcoming 13 sports subtle changes to the outsole and a fresh upper that looks nearly identical to the previous model.
What to Watch For
- Outsole Updates: Brooks adds Omega Flex Grooves to the outsole for improved flexibility and better gait efficiency. They also redesigned the arch bridge.
- New Upper: If you like the clean, simple lines of your Adrenaline 12s, you’ll feel right at home kickin’ it in the 13. Fit is unchanged, though there are now 3 elastic eyelets on the lateral side and redesigned placement of the elastic eyelets on the medial side, helping to create a more tailored fit.
