After my trusty running shoes finally gave up during a particularly brutal week of school pickups, grocery runs, and my evening yoga class, I found myself frantically googling “best running shoes for women” at 11:47 PM. Sarah here, and between juggling work deadlines and family life, I needed shoes that could handle my chaotic schedule without leaving my feet screaming by day’s end. That’s why I spent 8 weeks putting the Brooks Glycerin 21 through every real-world scenario I could think of. Here’s whether they live up to the premium price tag.

Design, Build Quality & Real-World Performance
Right out of the box, the Glycerin 21 feels substantial without being bulky. The engineered warp knit upper has this soft, almost stretchy quality that immediately felt accommodating around my foot. I have slightly wider feet, especially around the ball area, and I was pleasantly surprised by how the upper seemed to expand naturally with my foot shape.
The internal stretch bootie that Brooks talks about isn’t just marketing fluff – you can actually feel how it wraps around your foot differently than a traditional running shoe. It’s like the shoe is giving your foot a gentle hug rather than just containing it. During my first week of testing, I noticed this was particularly helpful during longer periods of standing at my daughter’s soccer practice.
Cushioning Experience & All-Day Comfort
The DNA Loft v3 cushioning is where these shoes really shine. I’ll be honest – I was skeptical about the “nitrogen-infused” marketing language, but after two months of daily wear, I understand what they’re going for. The cushioning feels responsive when you need it to be (like during my morning jogs) but soft enough for those 12-hour days when I’m constantly on my feet.
What impressed me most was the consistency. After 95+ miles of running plus countless hours of daily activities, the cushioning still feels fresh. I compared them side-by-side with my old New Balance 1080s (which I loved), and the Brooks definitely have a more substantial, cloud-like feel underfoot.
On-the-Road Performance
During my regular 5-mile Saturday morning runs, these shoes handle beautifully. The heel-to-toe transition feels smooth and natural – no awkward rocking or instability that I sometimes experience with heavily cushioned shoes. My usual pace is around 9:30 per mile (comfortable conversational speed with my running buddy), and the Glycerin 21s feel planted and confident at this effort level.
I tested them on various surfaces throughout my neighborhood: pavement, concrete sidewalks, packed gravel paths, and even some light trail sections. The rubber outsole provides reliable traction on dry surfaces, though I did notice they can feel a bit slippery on wet pavement – something to keep in mind for rainy morning runs.
Meeting Your Daily Life Goals – Does It Deliver?
Beyond just running, I needed shoes that could handle my real life: school pickups, grocery store trips, standing through kids’ activities, and evening walks with my family. The Glycerin 21 has become my go-to shoe for almost everything except formal occasions.
During a particularly hectic week where I was averaging 15,000+ steps daily (tracked via my Apple Watch), my feet felt remarkably fresh at the end of each day. The wide toe box gives my toes room to spread naturally, and the arch support feels just right – supportive without being intrusive.

Performance in Various Daily Conditions
I tested these shoes across numerous real-world scenarios that busy women face daily. During hot summer days (we had several 85°F+ mornings), the breathable upper kept my feet from feeling swampy during longer runs. The moisture-wicking properties worked well, though I did notice that on particularly humid days, I needed good running socks to prevent any hot spots.
For indoor gym workouts and yoga classes, the Glycerin 21 provided excellent stability during strength training exercises. The broad platform mentioned in Brooks’ marketing actually translates to noticeable stability during lateral movements, which was helpful during my weekly HIIT classes.
Standing for extended periods (think: kids’ sporting events, school functions, shopping trips) is where these shoes really proved their worth. After a 4-hour outdoor festival where I was constantly walking and standing, my feet felt remarkably fresh. My lower back, which sometimes aches with less supportive shoes, felt fine throughout the entire day.
Does Brooks Deliver on Their Promises?
Brooks makes some bold claims about the Glycerin 21, so let me break down how they held up during my real-world testing:
“Supreme softness with nitrogen-infused DNA Loft v3” – This lived up to the hype. The cushioning genuinely feels more premium than my previous running shoes. It’s soft without being mushy, responsive without being firm. Even after nearly 100 miles, the cushioning still feels consistent.
“Plush internal fit with stretch bootie” – Absolutely accurate. The internal bootie creates a noticeably different feel from traditional running shoes. It’s particularly beneficial if you have any foot shape irregularities or need a more accommodating fit.
“Smooth, stable transitions” – The heel-to-toe transition does feel smooth during running. I never experienced the “clunky” feeling that sometimes comes with heavily cushioned shoes. The broad platform definitely contributes to stability.
The one area where I’d temper expectations is the “lightweight” claim. At 9.2 oz, they’re not heavy, but they’re definitely not the lightest running shoes I’ve worn. For everyday activities and moderate-pace running, the weight is perfectly fine, but speed-focused runners might notice the difference.

What Other Women Are Saying
After reviewing hundreds of customer experiences, I found some consistent themes that align with my testing. Healthcare workers (nurses, CNAs) consistently praise these shoes for 12+ hour shift comfort. Many mention immediate relief from plantar fasciitis and foot pain.
The sizing feedback is remarkably consistent – almost everyone recommends going up a half size. Several customers mention the wide toe box as both a pro (for bunions and wide feet) and a con (for those preferring a more fitted look).
Durability experiences vary significantly. Some users report excellent longevity, while others experienced issues with toe box creasing or sole separation within a few months. This seems to be more related to individual use patterns and possibly quality control variations.
Value Assessment
At $160, the Glycerin 21 sits firmly in the premium running shoe category. Compared to similar cushioned options like the ASICS Gel-Nimbus ($160) or New Balance Fresh Foam X 1080 ($150), the pricing is competitive for this tier.
For busy women who need one versatile shoe that can handle running, daily activities, and long periods on their feet, the investment makes sense. The comfort factor alone has made these my default choice for almost everything, which increases their cost-per-wear value significantly.

Frequently Asked Questions
Do the Brooks Glycerin 21 run true to size?
Most women should size up a half size from their normal running shoe size. The Glycerin 21 tends to run small, particularly in length. If you wear a size 8 in most brands, consider ordering an 8.5. Those with wider feet may also want to consider the wide (W) option.
How do they compare to the previous Glycerin 20?
The Glycerin 21 features more cushioning with the updated DNA Loft v3 technology and a wider toe box compared to the 20. Most users find the 21 more comfortable for all-day wear, though some prefer the slightly more fitted feel of the 20.
Are these good for people with plantar fasciitis?
Yes, many users with plantar fasciitis report significant improvement when wearing the Glycerin 21. The substantial heel cushioning and arch support help reduce pressure on the plantar fascia. However, severe cases may still require custom orthotics.
How long do they typically last?
With regular use (3-4 times per week), most users report 300-500 miles before needing replacement. For daily wear including non-running activities, expect 8-12 months of use depending on activity level and body weight.
Can I use these for other activities besides running?
Absolutely! The Glycerin 21 is excellent for walking, gym workouts, standing jobs, and general daily activities. The cushioning and support make them ideal for anyone who spends significant time on their feet.
What’s the difference between the regular and GTS version?
The regular Glycerin 21 is for neutral runners, while the GTS (Go-To-Support) version includes GuideRails technology for mild overpronation. If you don’t have pronation issues, stick with the neutral version reviewed here.
Are they worth the $160 price tag?
For women prioritizing comfort and needing a versatile shoe for multiple activities, yes. The premium materials, advanced cushioning technology, and comfort factor justify the investment. However, budget-conscious buyers might prefer the Brooks Ghost 16 at $140.
How do I clean and maintain them?
Remove loose dirt with a soft brush, then clean with mild soap and warm water using a soft cloth. Air dry only – never put them in the dryer. The engineered mesh upper cleans easily and maintains its appearance well over time.
