On the run

Ghost 18: The classic, steady trainer. Moderately cushioned, steady and grounded. There’s no dramatic rocker or bounce, just a natural, familiar ride for easy and steady miles.

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.

Specs side by side

Stack, drop and weight come from each brand’s own website. Numbers marked * aren’t published by the brand and come from other published specs. Weights are for the size each brand quotes. Expected life is our estimate.

Fit

Ghost 18. True to size with a secure heel. It’s roomier than older Ghosts, but the forefoot still tapers, so wider feet should take the wide. Narrow through extra-wide.

Glycerin 23. Runs slightly short, so if you’re between sizes, go up a half. Roomy forefoot with more toe height than the 22; the stretchy upper can feel loose on narrow feet. Wide available.
