They both have been trying out the Brooks Glycerine 21, and let me tell you, they've got some thoughts to share. It's not just about how these shoes look but how they feel, the difference they make in a run, and why they might just be the next pair you decide to lace up. First let's talk about the history of the Brooks Glycerine. Let's get Nerdy!
A Short History of the Brooks Glycerine
How It All Began - The Brooks Glycerine
So, Brooks decided they wanted to make a splash in the early 2000s with a shoe that felt like running on clouds. Enter the Glycerin series. The name itself just screams smooth and cushy, right? It was their way of saying, "Hey, we're about to make your runs feel like you're gliding on glycerin."
The Tech Evolution
Over the years, Brooks really didn't sit back. They kept tweaking and innovating, making each Glycerin model a bit like a new episode in your favorite series - always something to look forward to.
- The Early Days (Glycerin 1 to 5): These were the pioneers, setting the stage with HydroFlow technology, basically fancy talk for making sure your feet felt steady and shock-free.
- The Middle Ages (Glycerin 6 to 9): This is when Brooks DNA made its debut. Imagine your shoes getting to know you better than some of your friends, adjusting to how you run, your weight, and even your pace. Pretty neat, huh?
- The Recent Innovations (Glycerin 10 to 15): They upped the ante with Super DNA, making the cushioning even more adaptable and introducing 3D Fit Print for a shoe that fits just right, no matter your foot shape.
- The Latest and Greatest (Glycerin 16 onwards): Here comes DNA LOFT, the softest, most luxurious cushioning yet. It's like they figured out how to bottle up a cloud and put it in your shoe. And they didn't stop there; the upper got more breathable and comfy, too.
Going Green
Lately, Brooks has been all about going green. They're throwing recycled materials into the mix and reducing their carbon footprint without skimping on quality. It's cool to see them taking steps to keep our planet as happy as our feet. We will discuss green composition in the sole further down.
Why Runners Love 'Em
The Glycerin series has built a bit of a fan club. Whether you're just jogging around the block or prepping for a marathon, these shoes have your back (or feet, in this case). They're known for lasting longer than your average TV show and providing that plush, supportive feel run after run.
I like how they have the perfect cushion for me. They are mid level everyday runner I find. They fit my foot perfectly, but I did go half a size up. They are fast and dependable shoe that I can wear on a long run, or a speed workout. Definitely my fave shoe I’ve worn in some time!

The Legacy
It's pretty clear the Glycerin series is more than just a line of shoes; it's Brooks showing off their commitment to making each run better than the last. They've become a staple for comfort-seekers and a symbol of how far running technology has come.
So, that's the scoop on the Brooks Glycerin series. It's been quite the journey from the early 2000s to now, and it seems like they're not slowing down anytime soon. Here's to many more miles in comfort and style!
What's the Hype about DNA Loft? - Nitro Injected Deep Dive into Nerd Town
Alright, let's dive into the world of nitrogen-injected shoes, which honestly sounds like something straight out of a sci-fi novel, but it's real and pretty cool.
So, imagine you're hanging out in a shoe factory, right? The folks there are working on making running shoes comfier and bouncier. Someone has a lightbulb moment: "What if we pumped nitrogen into the sole?" And that's where the magic begins.
Injecting nitrogen into the sole of a shoe isn't as simple as inflating a balloon at a birthday party. It's a high-tech process. First off, they start with the sole material, which is usually some form of EVA foam. EVA is like the bread and butter of running shoes; it's light, cushy, and pretty durable.
Now, instead of just leaving that EVA foam as is, manufacturers take it up a notch. They mix the EVA compound with nitrogen gas under pressure. This isn't something you do with a bicycle pump and a tank of nitrogen. It requires special machines and a controlled environment. The nitrogen gets infused into the foam, creating thousands of tiny bubbles.
Here's where the magic happens: those tiny nitrogen bubbles make the foam lighter and more responsive. When you step down, the foam compresses and then quickly bounces back, giving you a bit of a lift. It's like having tiny trampolines under your feet, making each step feel lighter and more energetic.
But why nitrogen, you might wonder? Nitrogen is stable and doesn't react much with other materials, which means the foam remains consistent over time and doesn't degrade quickly. Plus, nitrogen helps maintain the temperature inside the shoe, keeping your feet comfy as you run.
In simple terms, nitrogen-injected shoes are all about giving runners a springier step and more comfort without adding weight or reducing durability. It's a blend of chemistry and physics, all wrapped up in your sneakers. And the best part? You get to feel like you're running on air, or at least, on a cushion of nitrogen-infused foam, which is pretty awesome.
NERDY with Nitrogen: How they Do It
Sure thing, let's dive deeper into the supercritical fluid foaming process, focusing on how it's used to create those bouncy, nitrogen-injected soles in shoes like what Brooks offers.
The supercritical fluid foaming process sounds like something you'd stumble upon in a high-tech lab, and essentially, it kind of is. It's a method used not just in creating innovative shoe soles but also in various industries for different materials. Here's how it breaks down, especially in the context of shoe manufacturing:
Starting With The Basics: Supercritical Fluids
First up, a supercritical fluid is a state of matter that occurs when a gas (in this case, nitrogen) is subjected to temperatures and pressures above its critical point. It acquires unique properties that are somewhere between a gas and a liquid. It can flow through solids like a gas and dissolve materials like a liquid.
The Process in Shoe Manufacturing - The Special Sauce
1. The Base Foam: Brooks starts with a proprietary base foam. This foam is already pretty good on its own, designed for cushioning and support, but it's about to get a turbo boost.
2. Heating Up: The base foam is heated up, making it more receptive to the nitrogen that's about to be introduced. Think of this like prepping a sponge to absorb water more efficiently.
3. Pressure and Nitrogen Injection: Now, here's where the supercritical fluid comes into play. Nitrogen is turned into a supercritical fluid by applying heat and pressure beyond its critical point. This supercritical nitrogen is then injected into the heated foam. Because it's in a supercritical state, the nitrogen can penetrate the foam much more effectively than if it were just a gas or liquid.
4. The Magic Moment: While the supercritical nitrogen is infused throughout the foam, it starts doing its work. The nitrogen expands tiny bubbles within the foam, but uniformly, thanks to the even distribution capabilities of the supercritical fluid. This controlled expansion is crucial for creating a foam that's consistently cushioned across the entire sole.
5. Cooling Down: After the foam has been saturated with the nitrogen, the heat is reduced. This part is critical because as the mixture cools, the nitrogen tries to escape the foam, which creates an even more expanded, bubbly structure. However, because the foam solidifies as it cools, the bubbles are trapped, creating a permanently cushioned, lightweight structure.
6. Result: What you get is a sole that's not just lightweight and cushioned but also incredibly responsive. The nitrogen bubbles make the sole spring back more effectively with each step, giving you that feeling of running on air.
Why Supercritical Fluid Foaming?
The beauty of using supercritical fluid foaming lies in its precision and the quality of the end product. The process allows for a controlled, uniform expansion of the foam, ensuring that every part of the sole provides the same level of cushioning and responsiveness. It also allows for the creation of a material that's incredibly lightweight and durable, as the structure of the foam is strengthened by the trapped nitrogen bubbles.
This method is a perfect example of how advanced technology and an understanding of materials science are used to enhance our everyday products, like running shoes, making them more comfortable, efficient, and fun to use. It's pretty amazing what a bit of heat, pressure, and nitrogen can do to a piece of foam, isn't it?
ENOUGH NERDING OUT!

Brooks Ghost and Glycerin running shoes. They're both awesome options from the same brand but they have their own unique features that make them stand out.
So, the Ghost is kind of like the sturdy friend who's always reliable. It's got a midsole that's a bit on the firmer side, which means it gives you a nice mix of bounce-back and support. It's perfect if you like feeling a bit of firmness underfoot while still getting good cushioning. It's like having that extra push when you're out for a run.
On the flip side, the Glycerin is like the super comfy couch that you sink into after a long day. It's all about that soft, plush feel underfoot.
