Are we searching for a neutral daily trainer that gives us plush comfort without sacrificing a stable, predictable ride?
Overview of the Brooks Women’s Glycerin 20 Neutral Running Shoe
We find the Brooks Women’s Glycerin 20 to be a premium, highly cushioned neutral trainer aimed at runners who prioritize comfort on daily miles and long runs. The shoe emphasizes a soft ride and a smooth transition, which makes it a favorite for recovery days, longer easy runs, and anyone who loves a plush underfoot feeling.
First Impressions
When we first put the Glycerin 20 on, the immediate sensation is softness and a pillowy fit around the foot. The shoe presents itself as refined and purpose-built: it doesn’t look flashy, but it communicates comfort through every element of its construction.
Design and Materials
The overall aesthetic of the Glycerin 20 leans toward refined minimalism with a focus on function. The materials feel premium to the touch, and the shoe combines a soft upper with a generous midsole to create a balanced package for daily training.
Upper
The upper uses a knit-like, engineered fabric that wraps the foot comfortably while maintaining breathability. We appreciate the layered structure that provides structure around the midfoot and heel without feeling stiff or restrictive.
Midsole
The midsole is the star of the show: it is noticeably plush and offers a deep, cushioned experience underfoot. The foam is tuned to provide a balance of softness for comfort and responsive rebound for a smooth pedal through transitions.
Outsole
Brooks has placed durable rubber in high-wear zones of the outsole to give the shoe a longer lifespan on pavement. The tread pattern supports a smooth heel-to-toe roll, and the segmented design helps the shoe flex where our foot needs it most.
Cushioning and Ride
The Glycerin 20 delivers a plush, full-length cushion that makes even longer runs feel forgiving on joints. The overall ride is smooth, with the shoe absorbing impact efficiently and encouraging an easy, consistent turnover.
Plushness and Responsiveness
We experience deep softness when our feet land, coupled with a gentle rebound that keeps us moving forward. The cushioning doesn’t feel dead or sluggish; instead, it contributes to a comfortable but responsive sensation.
Heel-to-Toe Offset
The shoe features a moderate heel-to-toe offset that supports a stable landing and an efficient roll into the forefoot. This offset helps those of us with a natural heel-strike pattern feel balanced, while still allowing for a comfortable toe-off.
Fit and Sizing
Fit is generally straightforward: the Glycerin 20 tends to run true to size for most of us and accommodates a range of foot shapes. Brooks gives space in key areas while maintaining a secure midfoot hold, which makes it easy to select the usual size in our experience.
Toe Box and Width
The toe box offers a comfortable amount of room for our toes to splay naturally during longer runs. We don’t feel pinched, and there’s enough volume for those who prefer to add a thicker sock without compromising comfort.
Heel and Lockdown
The heel cup is structured enough to lock our foot into place, reducing slip and improving stability at higher cadences. The padded collar and snug heel pocket help maintain a secure fit without creating pressure points.
Weight and Performance
This shoe leans toward the heavier side compared to minimal trainers, but that weight works in favor of cushioning and durability. When we pick up the pace, the Glycerin 20 feels steady and comfortable rather than race-oriented, making it ideal for steady-state efforts rather than speed sessions.
Durability and Longevity
Because Brooks uses robust rubber in the outsole and a dense top layer in the midsole, we expect the Glycerin 20 to log many miles before showing significant wear. In our experience, shoes with a similar build typically last well for runners who use them primarily for daily training and long runs.
Breathability and Climate Suitability
The engineered upper fabric allows adequate airflow for most conditions, keeping our feet reasonably cool during moderate temperatures. In very hot, humid climates we might notice some warmth on prolonged efforts, while in cooler conditions the shoe provides enough coverage to remain comfortable.
Use Cases and Who It’s For
We recommend the Glycerin 20 for runners who prioritize cushioned comfort over lightweight speed. It’s an excellent choice for long runs, recovery days, walkers who want more cushioning, and runners who spend most of their time on pavement.

Ride Character and Mechanics
The ride character of the Glycerin 20 is deliberately plush and smooth, prioritizing comfort over raw responsiveness. That tactile softness gives our runs a cushioned feeling while still providing enough structure for a controlled stride.
Transition and Smoothness
Thanks to the full-length midsole and a well-shaped outsole geometry, the transition from heel-strike to toe-off feels linear and predictable. We never feel caught between zones; the shoe encourages a consistent rolling motion for relaxed cadence.
Energy Return and Propulsion
While the primary aim isn’t to maximize springiness, the cushioning provides a pleasant, slightly livelier push than old, flat plush midsoles used to offer. We get a comfortable amount of energy return that supports longer efforts without making the ride feel sluggish.
Stability and Support
Although marketed as a neutral shoe, the Glycerin 20 offers subtle supportive cues through its midsole geometry and structured upper. These design elements keep our stride in a stable plane of motion even when fatigue sets in on longer distances.
Ambulatory Control
The broad base underfoot and carefully tuned foam help control foot motion for everyday training. We notice a reassuring level of stability during pick-ups and moderate tempo efforts, which makes the shoe adaptable beyond just easy runs.
Support for Different Strides
Whether we land more on our heel or midfoot, the Glycerin accommodates different strike patterns without feeling off-balance. That flexibility is valuable for mixed-workout weeks where training pace and style might change.
Sizing Guidance
We find most runners do well ordering their usual Brooks size in the Glycerin 20, but it’s always worthwhile to try them on in-store or consult retailer size charts when possible. Our usual recommendation is to allow about a thumb’s width in the toe box for comfortable long-run swelling.
Sock Choice and Fit Impact
Using thicker socks will slightly reduce the internal volume, so we consider sock thickness when selecting the perfect fit for our training needs. If we plan to run long, hot days, choosing a thinner performance sock can help maintain fit without sacrificing comfort.
Adjusting Lacing for Comfort
We can fine-tune the fit with lacing—using a slightly higher lace bite for better midfoot hold or a lock lacing technique if the heel wants to slip. Small adjustments often change the feel dramatically, so it’s worth experimenting to get that perfect fit.
Comparisons to Other Brooks Models
Placed against other Brooks options, the Glycerin sits at the plush end of the neutral spectrum and pairs well against more versatile models. It tends to be softer than the Ghost and less propulsive than the brand’s springier models.
Brooks Glycerin 20 vs Glycerin 19
Compared to the previous generation, we notice refinements in upper comfort and midsole tuning. The update feels slightly smoother and more polished underfoot, with small improvements in breathability and fit.
Glycerin 20 vs Brooks Ghost and Other Neutral Shoes
Compared to the Ghost, the Glycerin 20 offers more cushion and a softer ride, while the Ghost tends to be slightly snappier and lighter. If our priority is plush cushioning for long runs, we lean toward the Glycerin; if we want a versatile daily trainer with a touch more responsiveness, we might choose the Ghost.

Who Should Buy the Brooks Glycerin 20?
We suggest the Glycerin 20 for runners seeking maximum underfoot comfort during long runs, those who prioritize joint-friendly cushioning, and walkers who want a softer ride. It’s ideal for runners who log consistent mileage and want a shoe that makes daily miles feel easier on the body.
Who Might Prefer Something Else
If we prioritize lightweight performance, race-day speed, or a very responsive, springy ride, we might look at alternatives like Brooks’ faster models or other brands’ more energetic foams. Also, runners who need strong corrective support for significant overpronation should consider structured stability shoes instead.
Practical Tips for Using the Glycerin 20
To get the most out of the Glycerin 20, we integrate it into a rotation that includes lighter, faster shoes for intervals and tempo days. Rotating shoes reduces wear on any single pair and lets us enjoy the Glycerin’s plush ride when we want comfort and longer distances.
Breaking It In
We don’t need a long break-in period for the Glycerin 20—its upper is soft and accommodating from the first run. Still, we recommend starting with shorter runs to confirm fit and to allow our feet to adapt to the increased cushioning, especially if we’re coming from firmer shoes.
Pairing With Orthotics
If we use custom orthotics, the Glycerin 20 usually has enough internal volume to accommodate them without compromising fit. We recommend trying orthotics with the shoe in-store if possible, and paying attention to sock thickness to maintain proper fit.
Care and Maintenance
To keep our Glycerin 20s in top condition, we clean them with mild soap and water and allow them to air dry away from direct heat. Avoiding machine washing and drying preserves the foam and upper materials, extending the lifespan of the shoe.
Storage and Rotation
Rotating shoes and storing them in a cool, dry place helps maintain foam resilience and outsole integrity. If we plan to store them long-term, keeping them in a ventilated box at room temperature is preferable to sealed plastic where moisture can accumulate.
Price and Value
The Glycerin 20 sits at the higher end of the daily trainer price range, but we feel the comfort, materials, and longevity justify the investment for many runners. If daily comfort and durability matter to us, the price per mile often ends up being reasonable given the shoe’s robustness.
Sales and Deals
We keep an eye on seasonal sales, previous colorway discounts, and retailer promotions to find a better deal without compromising on the exact fit or model year. Sometimes stepping down one model year brings notable savings with minimal perceived difference in performance for everyday runners.
Final Verdict
Overall, we see the Brooks Women’s Glycerin 20 as an excellent choice for runners who want a plush, comfortable neutral trainer that stands up to daily mileage. Its combination of soft cushioning, stable ride, and comfortable upper make it a practical and enjoyable shoe for long runs, recovery days, and anyone who values comfort first.
Frequently Asked Questions (FAQs)
Is the Brooks Glycerin 20 good for long-distance running?
Yes, the shoe’s plush cushioning and supportive ride make it well-suited for long distances and extended easy runs. We find it especially helpful on recovery weeks or when piling up mileage during base training.
How does the fit run compared to other Brooks models?
The Glycerin 20 typically runs true to size for most of us and offers slightly more volume in the toe box than some streamlined trainers. We recommend trying our usual size first and adjusting for thicker socks or orthotics if needed.
Can the Glycerin 20 handle speed workouts?
While we can use it for moderate tempo runs, the Glycerin 20 isn’t optimized for very fast intervals or racing due to its heavier, plush construction. For dedicated speed work, pairing it with a lighter, more responsive shoe in our rotation is a better strategy.
How long will the Brooks Glycerin 20 last?
Longevity depends on mileage and surface, but we expect the shoe to cover many miles—often well over 300 miles for neutral use—before showing major midsole compression or outsole wear. Regular rotation and avoiding excessive abrasive surfaces can extend its useful life.
Is the Glycerin 20 suitable for runners who overpronate?
The Glycerin 20 is a neutral shoe with mild intrinsic stability from its midsole and base; it may work for runners with mild overpronation. However, if we require substantial corrective support, choosing a dedicated stability model is the safer option.
What socks should we wear with the Glycerin 20?
A medium-thin performance sock usually offers the best balance of moisture management and fit for long runs. If we prefer extra padding, we can opt for thicker socks but should account for the reduced internal volume by considering a slightly larger size if our fit becomes snug.
Closing Thoughts
We appreciate how the Brooks Women’s Glycerin 20 prioritizes comfort without making compromises that feel frivolous or overbuilt. For runners and walkers seeking a plush, reliable daily trainer that cushions the miles and gives a consistent, smooth ride, the Glycerin 20 is a strong contender we’re happy to recommend.
