Fit & Sizing
Do the Ghost or Glycerin Run Narrow?
The answer is slightly different for each.
The Brooks Ghost is true to size with an accommodating fit through the midfoot and forefoot. It's available in narrow, standard, wide, and extra-wide widths, making it one of the most inclusive options in the Brooks lineup. Most runners can order their usual size; the engineered mesh upper provides enough give to accommodate a range of foot shapes without feeling sloppy. Try both pairs in DSW stores to confirm fit and width if you're unsure.
The Glycerin tends to fit slightly snugger in the toe box despite its plush interior. The cushioning wraps more closely around the foot, which creates a cozy, sock-like feel, but runners with wider forefeet may want to try a wide width or go up a half size. The Glycerin is available in narrow, standard, and wide options, though it lacks the extra-wide sizing offered by the Ghost.
If you're between sizes or have broader feet, the Ghost is generally the safer bet for an out-of-the-box comfortable fit.
Ride Feel
The ride is where these two shoes diverge most noticeably.
The Ghost uses Brooks' DNA LOFT v2 foam, which provides a balanced, medium-cushioned feel. It's responsive enough for tempo-day easy runs and supportive enough for walking or standing throughout the day. The 12 mm drop promotes a smooth heel-to-toe transition, and the midsole balances softness and firmness. This versatility is why the Ghost has been one of the best-selling running shoes in America for years, according to Brooks Running.
The Glycerin uses nitrogen-infused DNA LOFT v3 foam, which is noticeably softer and more cushioned. The higher stack height (38 mm in the heel) creates a plush, pillowy sensation underfoot that absorbs impact well on long runs and high-mileage days. The 10 mm drop is slightly lower than the Ghost's, which some runners prefer for a more natural foot position. If your priority is maximum comfort, whether you're logging 10-mile runs or spending a full day on your feet, the Glycerin provides a more luxurious ride.
The Ghost is a reliable daily trainer that can do a bit of everything, while the Glycerin is a premium comfort shoe built for runners who prefer a very soft underfoot feel.
Durability
Both the Ghost and the Glycerin are built to last, and Brooks has a reputation for producing shoes that hold up over hundreds of miles.
The Ghost's outsole features strategically placed rubber pods and flex grooves that resist wear while maintaining flexibility. Runners report getting 300–500 miles out of the Ghost before the cushioning begins to flatten, which is on par with or better than most shoes in its price range. The engineered mesh upper also holds its shape well over time.
The Glycerin uses a similar rubber outsole with a slightly expanded contact area to match its wider platform. Because the DNA LOFT v3 foam is softer, some runners notice the midsole compresses a bit faster than the firmer Ghost foam, particularly for heavier runners or those putting in high weekly mileage. The Glycerin generally delivers longevity in the 300–450 mile range for most users.
If durability is a top priority and you want your shoes to maintain their cushioning feel for as long as possible, the Ghost's firmer foam has a slight edge. If you'd rather have maximum softness and don't mind replacing shoes a bit sooner, the Glycerin remains an excellent choice.
