If you're looking for a neutral running shoe with plenty of cushioning for easy miles, recovery runs, long runs, or all-day comfort, the Brooks Glycerin 23 is worth a closer look.

Bottom Line

The Brooks Glycerin 23 improves on the Glycerin 22 with a better fit, slightly softer ride, and additional forefoot cushioning. While it faces stiff competition from other premium cushioned running shoes, it remains one of the most dependable daily trainers available.

What's New in the Brooks Glycerin 23?

Before we can figure out where the updated Glycerin sits, we need to understand the changes Brooks made.

Updated Knit Upper

The Glycerin 23 features a new triple jacquard wrap-knit upper that feels softer and more durable than the previous version.

While comfort improves, breathability takes a small step backward. Runners who tend to run hot may notice less airflow during summer training.

More Forefoot Cushioning

Brooks added 2mm of foam to the forefoot. While the difference isn't dramatic, it creates a softer ride and improves comfort during longer runs. The added foam also lowers the shoe's drop from 10mm to 8mm.

Redesigned DNA Loft v3 Foam

The DNA Loft v3 midsole remains nitrogen infused, but Brooks has adjusted the foam structure to improve comfort and impact absorption. The heel feels softer on landing while the forefoot maintains enough structure to keep the ride stable.

Brooks Glycerin 23 Fit and Sizing

One of the biggest complaints runners had about the Brooks Glycerin 22 was the fit. The shoe ran short, felt shallow through the toe box, and created pressure across the top of the foot for some runners. Fortunately, Brooks addressed those concerns. The Brooks Glycerin 23 fits much more naturally. Length feels true to size, toe box volume has improved, and the upper no longer presses aggressively on top of the foot. Most runners should feel comfortable ordering their normal running shoe size.

Brooks Glycerin 23 Performance Review

How Does the Brooks Glycerin 23 Feel on the Run?

On the run, the Brooks Glycerin 23 provides a soft and comfortable experience. The additional forefoot foam helps smooth out landings while the redesigned DNA Loft v3 foam delivers a gentle bounce that feels more protective than responsive.

The shoe shines during:

  • Easy runs
  • Recovery runs
  • Long runs
  • Walking
  • All-day wear

I particularly enjoyed the lower 8mm drop and secure heel lockdown. My foot felt stable throughout the run and I never experienced heel slippage. The biggest drawback was heat retention. The updated upper feels warmer than previous versions and airflow is noticeably reduced.

Brooks Glycerin 23 vs Brooks Glycerin 22

The Glycerin 23 isn't a complete overhaul, but it's clearly the better version.

Improvements Over Glycerin 22

  • Better fit

  • More toe box volume

  • Softer forefoot cushioning

  • Lower 8mm drop

  • More comfortable upper

Drawbacks Compared to Glycerin 22

  • Less breathable

  • Slightly heavier

For most runners, the improved fit alone makes the Glycerin 23 the better choice.

Brooks Glycerin 23 vs Brooks Ghost Max 3

Many runners deciding between Brooks' premium trainers will compare the Glycerin 23 and Ghost Max 3.

Choose the Glycerin 23 If:

  • You prefer a traditional running shoe feel

  • You want a lower stack height

  • You value versatility

Choose the Ghost Max 3 If:

  • You want maximum cushioning

  • You prefer a rocker-based ride

  • Recovery runs are your primary focus

Brooks Glycerin 23 vs Hoka Clifton 10

The Hoka Clifton 10 remains one of the Glycerin's biggest competitors. The Clifton offers a lighter and more rockered ride, while the Glycerin 23 provides a more traditional feel with stronger durability and stability. Runners seeking a classic daily trainer may prefer the Glycerin 23, while those wanting a highly cushioned, rolling ride may gravitate toward the Clifton.

Who Should Buy the Brooks Glycerin 23?

The Brooks Glycerin 23 is best for:

  • Neutral runners

  • Marathon training

  • Long runs

  • Recovery runs

  • Walkers

  • Runners seeking comfort and durability

Final Verdict: Is the Brooks Glycerin 23 Worth It?

The Brooks Glycerin 23 improves upon nearly every weakness of the Glycerin 22.

The fit is better, the ride is softer, and the overall comfort level is improved. While the shoe gains a little weight and sacrifices some breathability, Brooks successfully delivers a more refined daily trainer.

It may not be the softest shoe in the max-cushion category, but it continues to offer the combination of durability, stability, and comfort that Brooks is known for.

For runners looking for a dependable cushioned running shoe for everyday mileage, the Brooks Glycerin 23 remains one of the strongest options on the market.

Brooks Ghost 18 Review: The Reliable Daily Trainer Gets Better

Brooks Ghost 18 Review: The Reliable Daily Trainer Gets Better

Looking for a dependable daily trainer that can handle everything from easy miles to long runs? In this Brooks Ghost 18 review, I'll cover the fit, ride, updates from the Ghost 17, and whether this popular running shoe deserves a spot in your rotation. Brooks Ghost 18 At a Glance Category: Daily TrainerSupport: NeutralWeight: 10.2 oz (Men's) / 9.2 oz (Women's)Drop: 10mmBest For: Daily training, easy runs, walking, long runsRide Feel: Smooth, cushioned, and reliablePros: Improved fit, comfortable upper, versatile ride, great durabilityCons: Runners seeking a highly energetic or max-cushioned ride may prefer other options Brooks Ghost 18 Review If I had to describe the Brooks Ghost with one word, I would say reliable! For years, the Brooks Ghost has been one of the most trusted daily trainers on the market. Runners know what they're getting: comfort, durability, and a smooth ride that can handle just about any type of run. When Brooks released the Ghost 17, they made some of the biggest updates the line had seen in years. While the changes took some getting used to for longtime fans, Brooks clearly wasn't afraid to innovate and try something new. Now, with the Brooks Ghost 18, I think Brooks has found a great balance between modernizing the shoe and maintaining the dependable feel that made the Ghost so popular in the first place. While it doesn't completely return to the fit and shape of older models, the Ghost 18 builds on what worked in the Ghost 17 and refines several areas that runners were paying close attention to. What's New in the Brooks Ghost 18? One of the biggest updates to the Brooks Ghost 18 is the fit of the upper. The shoe still features a slightly more streamlined toe box than older Ghost models, but Brooks has done an excellent job creating more room through the forefoot. The result is a fit that feels comfortable and accommodating without sacrificing the secure lockdown that many runners appreciate. Brooks also appears to have fine-tuned the sizing. The Brooks Ghost 18 feels more natural on foot and provides a more dialed-in fit right out of the box. It's a subtle improvement, but one that many runners will notice immediately. My favorite update has to be the new flat, flexible tongue. It sits comfortably across the top of the foot, stays in place during runs, and provides just enough cushioning to keep the laces comfortable. Brooks has used similar designs in some of their faster shoes, so it's exciting to see that technology make its way into one of their most popular daily trainers. The new triple jacquard mesh upper is another welcome addition. It gives the shoe a more premium look while maintaining the breathability and comfort runners expect from the Ghost. Combined with the DNA Loft v3 midsole, the ride feels soft, smooth, and surprisingly responsive for a daily trainer. Brooks Ghost 18 Fit and Sizing One of the most common questions runners have is whether the Brooks Ghost 18 fits true to size. Compared to the Ghost 17, the Ghost 18 feels more dialed in and natural. The additional room in the forefoot allows the shoe to feel accommodating without becoming sloppy, while the heel and midfoot remain secure throughout the run. Most runners should be comfortable ordering their normal running shoe size. If you found the Ghost 17 slightly long, you'll likely appreciate the refinements Brooks made with the Ghost 18. Brooks Ghost 18 Performance Review: On the Run Of course, none of the updates matter if the shoe doesn't feel good once you start running. The Brooks Ghost 18 delivers exactly what most runners expect from the Ghost line: a smooth, comfortable ride that disappears on your foot. From the first few steps, the DNA Loft v3 foam provides a soft landing without feeling overly squishy. There is enough cushioning to keep easy miles comfortable, but the shoe still has enough responsiveness to pick up the pace when needed. What impressed me most was how natural the transition feels from heel strike to toe-off. The Ghost has never been a flashy shoe, and the 18 doesn't try to be one. Instead, it focuses on creating a consistent ride that feels reliable mile after mile. Whether I was heading out for an easy recovery run or knocking out a longer training session, the shoe felt stable and predictable. The updated upper also shines once you're moving. The extra room in the forefoot allows your foot to spread naturally throughout the run, while the heel and midfoot remain secure. Combined with the flexible tongue, the entire package feels comfortable without requiring much adjustment. Runners looking for a super-soft max-cushion shoe or an aggressive speed trainer may want something different. However, for those who want a dependable daily trainer that can handle most of their weekly mileage, the Brooks Ghost 18 continues to do what the Ghost has always done best: make running feel easy. Brooks Ghost 18 vs Ghost 17 The biggest difference between the Brooks Ghost 18 and Ghost 17 is refinement. While the Ghost 17 introduced a new fit and feel for the franchise, the Ghost 18 builds on those changes and improves the overall experience. The forefoot feels more accommodating, the sizing feels more consistent, and the new tongue design enhances comfort. If you enjoyed the Ghost 17, you'll likely appreciate the improvements found in the Ghost 18. If you were hesitant about the Ghost 17's fit, the Ghost 18 may be worth another look. Brooks Ghost 18 vs Hoka Clifton 10 The Brooks Ghost 18 and Hoka Clifton 10 both compete in the daily trainer category, but they offer different experiences. The Ghost 18 provides a more traditional running shoe feel with a balanced amount of cushioning and a stable ride. The Clifton 10 offers a softer, more cushioned experience that many runners prefer for recovery days and high-mileage training. Runners looking for a dependable all-around trainer may gravitate toward the Ghost 18, while those seeking maximum cushioning may prefer the Clifton 10. The Final Verdict The Brooks Ghost 18 feels like a confident step forward for the franchise. Brooks listened to feedback, refined the fit, and delivered a shoe that remains true to the dependable identity that Ghost fans have loved for years. Whether you're a longtime Ghost runner or someone looking for a comfortable everyday trainer, the Brooks Ghost 18 deserves serious consideration. It stacks up well against other popular options in the category and continues to prove why it's one of the most trusted names in running. For runners who may have been unsure about recent updates to the line, I think the Brooks Ghost 18 is worth a look. Brooks continues to show why they're one of the most consistent brands in the industry, and the Ghost 18 is another example of that commitment to improvement. It may not be the flashiest shoe on the wall, but it delivers exactly what a daily trainer should: comfort, reliability, and a ride that keeps you coming back for more miles. Brooks Ghost 18 FAQ Is the Brooks Ghost 18 good for beginners? Yes. The Brooks Ghost 18 offers a comfortable, stable ride that works well for both new and experienced runners. Does the Brooks Ghost 18 fit true to size? For most runners, yes. Brooks refined the fit compared to the Ghost 17, resulting in a more natural and consistent sizing experience. Is the Brooks Ghost 18 good for walking? Absolutely. The comfortable cushioning and durable construction make it a strong option for walking and all-day wear. Who should buy the Brooks Ghost 18?
