On the run

Glycerin GTS 23: Plush, premium stability. Cushioned but surprisingly firm and dense, like the Glycerin 23, with GuideRails that guide without feeling restrictive. It feels softer walking than running.

Glycerin 23: The plush luxury cruiser. Deep, plush cushioning with a soft heel. It’s built for comfort, not speed, and the forefoot needs a couple dozen miles to loosen up.

The Glycerin GTS 23 hasn’t been lab tested by RunRepeat yet, so its feel ratings are estimated from the Glycerin 23 lab test (same DNA Tuned foam), RTINGS’s lab test and Doctors of Running’s review.
