Glycerin 23
Glycerin 23 is a high-cushion road trainer for daily mileage and long runs. An extra 2mm of nitrogen-infused DNA TUNED foam under the forefoot supports toe-off while retaining soft landings. A broad platform and tuned heel-to-forefoot geometry promote smooth, stable transitions. The new engineered-knit upper combines breathability with a soft, accommodating fit for sustained comfort.
