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 GTS 22: Plush support for long runs. Very stable and impressively cushioned, with all-day comfort. The EVA-based foam doesn’t give much energy back.
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.
