Brooks Glycerin vs Adidas Ultra Boost

Picking the proper footwear is vital to keep the health of your feet. When wearing the fittest shoes for you, you can be more active in physical activities while also be more protected against injuries.

You can be more comfortable as the shoes fit you to support your activities throughout the day while protecting your feet parts. Now, what are the right shoes for you?

We have four criteria for this, namely cushions, supports, feel, and fit. The shoes have the right cushioning part that clicks with you. The midsole is the central part of a shoe that provides cushioning to increase the time taken for force to apply.

Your shoes should support or aid the alignment of your foot right when it touches the ground. They should be comfortable when the first time you wear them, don’t force yourself to them. When measuring the size, make sure that you left one to one and a half centimeters to provide more room for your feet. This size should be broad and long enough to fit your feet.

Choosing the right shoes is tricky, especially when there are thousands of them in the market. But we have come with recommendations, the Brooks Glycerin and Adidas Ultra Boost. Which one of these shoes is worth buying? Let’s find out!

Adidas Ultra Boost

Nowadays, who doesn’t know the name of Adidas? Ultra Boost is one of the essential shoes in the past decades. With the arrival of 21, Ultra Boost keeps making its popularity on the rise. The original idea was to combine high-performing technologies with a commendable, superb design and show that it’s Adidas.

The Innovative Boost foam also promoted Adidas’s name as the leader in the sports shoe market. The Boost foam is designed for street lovers, triggering a revolution in energy feedback. Read also: Brooks Revel 3 Vs Launch 6.

We can say that Ultra Boost is the top of its kind. With them, your feet can fit right away without the hustle and giving the nicest cushion possible. Many say it’s the best of both worlds. It performs well while also making you look more stylish. But, some problematic dots are found and making the shoes not the best version for daily runners.

What Ultra Boost 21 is the total redesign in fundamental. Of course, through the course of history, other Ultra Boosts version also received their own redesigns. But, none can surpass the updated visual as good as 21.

While the shoe is looking nice, it still carries many similarities, including the Boost foam, Prime knit upper, and other elements. But, due to the redesign, now the midsole is made and felt better with the heel frame gone and higher foam stack.

What Adidas did was increasing the foam by 6%, and no, it’s not a random dice number. Though small in number, it’s noticeable in practice. This number was the result of trial and error processes done by the designing team. They found 6% as the actual balance of comfort and responsiveness.

You can say that the shoes are a product of a new torque system due to their excellent responsiveness when used for running. This is called the Linear energy Push System, located under the midsole. According to Adidas, the bending stiffness has increased by 15% from the previous series. That’s why it’s now more responsive and enjoyable to wear for a fast-paced run.

Brooks Glycerin

The second one we have here is Brooks Grycelin 19, the softest shoe of Brooks. While you can buy Glycerin 19 GTS, you can also get the Go-To version, adding an additional value fit for runners. The Guide Rails technology is not to be neglected.

Brooks keeps extending the DNA loft in the cushioning part, making it the entire length of the midsole. We can say this shoe is better for the marathon because the heel-to-toe experience is made softer now. The design fits multi-gender, but many considered it one of the best shoes for women.

Now, Grycelin shoes come with GTS technology. This feature is specifically made for runners who aren’t fans of neutral shoes. The system will support your feet like a stabilizer on a bicycle. The result is a reduction in shin rotation and pronation.

Inside, there are two pieces of foam on the heel side of the midsole. Going to the heels’ inside, the foam reduces the inward rolling. On the outside, the foam is firmer and placed higher to minimize the shifting of the heel. The goal is basically to make your knee motion in range, therefore reducing the risk of joints pain.

The plush, however, extends to the upper side, which can fit your feet tightly. The shoes are made simpler with not edge and rub. The fit is further supported by adding an OrthoLite sock liner which also has the spongy depth.

To better promote comfort, Brooks also includes the DNA Loft, a personal technology by Brooks. The reason this exists here is to improve cushioning while making the shoes lighter. This feature alone is only presented in the 19 version of it. That’s why it’s worth getting the 19 instead of the previous 18. The outsole rubber also feels durable, especially the outside heel.

You can choose one from three colors, Ice Flow, Navy, and Pink, further fitting the user’s style. The ice flow is the neutral one, while the pink and navy give off their unique vibes. If you want to be edgier, the Pink one is more suitable. There are other choices as well, like Black and Blue.
