What Makes the Brooks Glycerin 23 Different?

The Glycerin family is known for premium cushioning and everyday comfort. The Glycerin 23 continues this approach with DNA TUNED technology, which uses nitrogen-infused foam with different cell structures to balance softness and responsiveness within the midsole.

The goal is to provide a comfortable landing without making the ride feel unnecessarily sluggish. The shoe is designed to support the repetitive loading of road running while maintaining a smooth transition from initial contact through to toe-off.

Unlike a carbon-plated racing shoe, the Glycerin 23 focuses on training comfort and versatility. It is particularly relevant for runners who want to accumulate kilometres in a well-cushioned shoe rather than prioritise the lowest possible weight or an aggressive race-day feel.

DNA TUNED Cushioning Technology

DNA TUNED is Brooks' nitrogen-infused midsole technology. Its construction is designed to create a combination of cushioning and responsiveness, with the foam tuned to deliver a softer sensation in the heel and a more energetic response towards the forefoot.

Soft landings for everyday road running

Running on hard surfaces creates repeated impact through the feet and lower limbs. The Glycerin 23's substantial cushioning is designed to make each landing feel comfortable during regular training, particularly when you're accumulating distance over several sessions each week.

Responsive toe-off

A highly cushioned shoe should still allow you to move naturally through your stride. DNA TUNED is designed to balance a plush landing with a responsive forefoot sensation, making the Glycerin 23 suitable for more than just very slow recovery running.

Consistent comfort over distance

The Glycerin 23 is designed for runners who value comfort throughout a session. Whether you're completing an easy 5 km or extending your long run, the cushioning platform aims to deliver a consistent ride that supports regular training.

8 mm Heel-to-Toe Drop and Running Geometry

The Glycerin 23 has an 8 mm heel-to-toe drop, meaning the heel sits higher than the forefoot by that amount. This geometry will feel familiar to many road runners, although the best drop for an individual depends on comfort, running mechanics and personal preference.

The shoe's cushioned platform is designed to support smooth transitions rather than force a particular foot-strike pattern. Heel strikers, midfoot strikers and forefoot strikers should choose footwear based on how it feels and performs for them, not solely on the drop measurement.

Engineered Mesh Upper: Breathability and Secure Fit

The engineered mesh upper is designed to provide airflow, a comfortable fit and support during repetitive movement. The upper works with the lacing system to help hold the foot securely without unnecessary pressure across the midfoot.

• Breathable construction: Supports airflow during everyday training and longer runs.
• Secure midfoot fit: Helps keep the foot positioned over the cushioning platform.
• Comfort-focused design: Supports repeated use across regular training sessions.
• Toe-box comfort: Allows natural toe movement when the correct size and width are selected.

For longer runs, the fit should allow enough room for your toes to spread while preventing excessive heel movement. A shoe that feels comfortable immediately is a good starting point, but it should also remain comfortable when walking or jogging.

Outsole Grip and Road Durability

The outsole is designed to provide traction on typical road-running surfaces, including tar roads, pavements and maintained paths. Its rubber coverage helps protect the shoe against repeated contact with the ground during regular training.

The Glycerin 23 is primarily a road-running shoe. It is not intended to replace a dedicated trail model on muddy, rocky or technical terrain.

Who Should Choose the Brooks Glycerin 23 Men's?

Runners who prioritise cushioning

If you prefer a soft, protective ride over a firm or minimal feel, the Glycerin 23 is designed around that preference. Its premium cushioning makes it a strong candidate for everyday road running.

High-mileage runners

Runners completing multiple sessions each week may appreciate a shoe built around comfort and consistent training. The Glycerin 23 can serve as a main daily trainer for easy and steady mileage, depending on individual fit and durability needs.

Recovery-run specialists

After intervals, tempo running or a demanding long run, some runners prefer a more cushioned shoe for their next easy session. The Glycerin 23 is well suited to this comfort-focused role.

Half-marathon and marathon runners

The cushioning and smooth ride make the Glycerin 23 worth considering for regular training and longer runs. Runners preparing for a marathon should test the shoe across progressively longer distances before relying on it for race day.

Comrades Marathon runners

For Comrades preparation, the Glycerin 23 may be suitable for easy mileage, recovery sessions and long runs if its cushioning and fit suit your mechanics. Long-distance preparation involves substantial cumulative loading, so comfort, secure fit and reliable performance over extended sessions are essential.

Runners seeking an everyday comfort shoe

The Glycerin 23 is not restricted to competitive athletes. It is also worth considering for recreational runners who want a premium cushioned shoe for regular exercise and general road-running fitness.

Who Might Prefer a Different Running Shoe?

• Runners seeking a lightweight racing shoe: A dedicated performance model may be better suited to fast intervals and race-day priorities.
• Runners who prefer a firm ride: The Glycerin 23 is designed around premium cushioning and may feel too plush for runners who prefer a firmer, more direct connection with the road.
• Runners needing structured stability: Consider a stability-focused model if your footwear assessment indicates that additional support features would be beneficial.
• Runners with wide feet: Check the available width options and ensure the forefoot is not compressed.
• Trail runners: Choose footwear with a trail-specific outsole and upper for uneven or technical surfaces.

Fit and Sizing Advice

The right fit should feel secure through the heel and midfoot while leaving sufficient room for the toes. Foot dimensions can change during longer runs, so avoid a fit that feels restrictive from the start.

• Allow approximately a thumb's width of space in front of your longest toe.
• Check that the heel stays secure without excessive slipping.
• Ensure the forefoot is not squeezed from the sides.
• Try both shoes on, as your feet may differ slightly in size or shape.
• Use your usual running socks when assessing fit.

If you have a broad forefoot or need extra volume, compare the available width options rather than simply buying a longer size. Length, width and overall foot containment all contribute to a comfortable fit.

What is the heel-to-toe drop of the Glycerin 23?

Is the Glycerin 23 suitable for heavy runners?

Runners of different body weights may find its cushioning comfortable, but body weight alone does not determine the right shoe. Fit, comfort, running mechanics and individual support needs should guide the decision.

Is the Glycerin 23 suitable for speed work?

It can handle moderate changes of pace, but its main purpose is comfortable daily training. Runners who frequently complete short, fast intervals may prefer a lighter, more performance-oriented shoe.

Does the Glycerin 23 have a carbon plate?

No. The standard Glycerin 23 is a cushioned daily trainer rather than a carbon-plated racing shoe.

Is the Glycerin 23 available in wide sizing?

Brooks offers selected models in different widths, but availability varies by market, size and colourway. Check the exact version available before purchasing.

How long should the Brooks Glycerin 23 last?

Actual lifespan depends on mileage, runner weight, running surface, gait, care and shoe rotation. Inspect the outsole, midsole and upper regularly, and replace the shoe when its cushioning feel, fit or structural integrity deteriorates noticeably.
