Overview of the Brooks Glycerin 21 and Glycerin GTS 21

When looking at both Glycerin models they're made for different kinds of feet and running styles. I've run marathons and tried out tons of shoes, so I know how important it is to find the right fit.

The Glycerin 21 is super comfy and soft, perfect for runners like me who just want to feel like they're running on clouds. I remember wearing them during a long training run and hardly feeling tired at all – they were that good at soaking up the impact.

Then there's the Glycerin GTS 21, which is a bit different. It's designed for runners who need extra support because their feet roll inwards a bit when they run. This is important because the wrong shoe can lead to injuries. I had a friend who always struggled with this, and once they switched to this shoe, they could run longer distances without pain.

Both shoes are well-designed, but they're made for different needs. What I've learned from my year's of running and helping others find their gear is that there's no one-size-fits-all. You have to think about what your feet are like and how you run. The right shoe makes all the difference – it can help you run further, faster, and without getting hurt.

Midsole Comparison: DNA Loft v3 Foam and GuideRails Support

The Glycerin models stand out for using a high level of cushioning. Its amazing foam helps your feet stay fresh for a longer time. It's soft, but it also bounces back, so I don't feel like I'm losing energy with each step. This is great for someone like me who just runs without worrying too much about how my foot lands.

Then, there's something for runners who might need a bit more help with their forefoot movement. It's called GuideRails. Think of it like those bumpers they put up at bowling alleys for kids but for your feet. They don't force your feet to move a certain way; they just gently guide them if they start to go too far to one side.

In my experience, whether you're just out for a casual jog or pushing through the last miles of a marathon, having the right support under your feet can make all the difference. And it's not just about finishing the race; it's about how you feel during and after.

Design and Performance

When looking at two types of running shoes, one thing stands out to me from years of running marathons and helping people find the right gear: both are great for making runs smooth, but they suit different runners. They both have a soft and bouncy feel when you step down because of the special foam used in them. However, one has something extra called GuideRails that helps runners who tend to roll their feet inwards too much when they run, keeping them stable without messing with their natural step.

From my experience, the first shoe is perfect for runners who don't have issues with their feet rolling in or out too much. It's super comfy and responsive, making it my go-to for long runs or everyday training. The second shoe, with its extra support, is a lifesaver for runners like a friend of mine who struggles with overpronation. During a marathon training season, they switched to this shoe, and it made a huge difference in preventing knee pain they used to have because of their running form.

In picking between these two, it's all about understanding your running style and what your feet need for support. I've seen firsthand how choosing the right shoe can turn a struggle into a stride, both in my runs and for countless customers.

Outsole and Upper

When looking into these running shoes, I noticed something cool about the top part and the bottom part that helps with running. The top part is made of this airy material that lets your feet breathe and feel comfortable, even when you're running for a long time. It fits your foot just right, so you don't feel any discomfort no matter how far you run.

For the outsole of the shoe, here's a few things to talk about:

  • 1. The material they use outsole is soft and does a great job of soaking up the shock when your foot hits the ground. This makes each step feel smoother.
  • 2. The way the outsole is designed helps your foot move naturally and easily. It doesn't make your foot feel stiff or awkward when you're running.
  • 3. Some shoes have extra support on the outsole to help people who might run in a way that could cause them pain. This extra support isn't too much; it's just right to help keep your run comfortable without messing up your natural running style.

From my experience, having shoes that can breathe well and keep your feet feeling good makes a big difference, especially on long runs. The outsole design helps in making sure each step feels good and keeps you running the way you naturally do.


After checking out many shoes for running, it's important to talk about how tough some are. In this regard, both Glycerin 21 and Glycerin GTS 21 stand out. They have a strong outsole, which is great because it won't fall apart quickly. This bottom part also helps keep a good grip on the ground during runs, which is super important when running in different places.

They also have this new kind of top part that helps your feet breathe while making sure the shoe doesn't get loose or break easily. This is a big deal because some running shoes don't last long before they start to fall apart.

From my runs, I can say these shoes are really on the same level when it comes to lasting a long time. The way they're made, from the bottom to the top, means they don't just feel good; they're also a smart pick for runners who want their shoes to last.

Comfort and Cushioning

Brooks Glycerin vs Glycerin GTS

When choosing the right running shoes, comfort and support are key. I've run in many different pairs, and I've found both Brooks shoes stand out for their cushioning and support, making long runs feel much better.

These shoes have a special foam that makes them super soft. I remember running a half marathon and feeling like I was running on clouds. They didn't make my feet tired or sore, which was amazing.

Then, there's another pair for runners who need a bit more help with their foot movement. They use the same soft foam but add something extra to keep your feet in the right position. I've seen this help a lot during my longer training sessions, especially when my legs start to get tired. It's like having a guide that keeps everything aligned, which helps prevent soreness.

Both Glycerin models are super comfy, but if you're just running for fun and don't worry much about your foot movement, the Glycerin 21 might be better. However, if you're like me and need a bit more support to keep your run smooth, the Glycerin GTS 21 is a great choice. It's all about finding the right balance for your feet, and I love helping others find that perfect pair.

Final Verdict

In this Brooks Glycerin vs Glycerin GTS shoe review, we've explored in-depth the ins and outs of both running shoes. The bottom line is choosing the right one depends on your unique needs. If you're someone who appreciates supreme comfort and cushioning without the need for extra support, the Brooks Glycerin 21 is your go-to, perfect for those long, cloud-like runs.

On the flip side, the Glycerin GTS 21 stands out for runners needing more stability to avoid injuries, thanks to its GuideRails support that gently corrects overpronation. My firsthand experience, along with feedback from fellow runners, underscores the importance of matching your shoe to your running style.
