Glycerin 14 $150

As it motors toward a decade and a half, the Glycerin is a testament to staying power. Building solidly on the strengths of Rounds 12 and 13, the Glycerin 14 emphasizes plush high-mileage comfort. The upper shows a concerted effort to stabilize the midfoot and improve the vamp by reshaping the saddle and using thinner, printed overlays between the saddle and toe.

The flexibility of the upper is also improved by the use of Stretch Print, 3D-printed polymer strands with elastic properties that conform to the foot’s movement. The midsole has been thoroughly dialed in from Round 13, with the usual minor changes this type of update brings. The outersole has closed a bit of the open area in the midfoot by adding a few strips of rubber, discernible to only the most sensitive runners. By improving the fit, shaving off a few grams of weight, and improving the smooth feel and ride, Brooks has made this update a success.

Testers: “Fit really well, and the plush feel made the ride pretty amazing.”
