Brooks Glycerin 18 | Features, Price and Featured Opinions
We analyze the characteristics of Brooks Glycerin 18, one of the models that always appears in the rankings of the best daily training shoes, with better cushioning or neutral shoes, to put several examples of categories where it stands out.
Because it is true since (in other words): this daily training shoe focused on runners and runners with a neutral tread or insole and who are looking for a lot (and good) cushioning plus comfort ..., it cannot be reaching two decades in the asphalt without being a good piece.
The fact is that the American brand maintains it, along with its "sister" for pronating tread Brooks Adrenaline GTS 20, as two of its longest-lived models.
The profile of the shoe is still like the first day of Glycerin 1, but of course the materials are not. Now, the midsole uses a non-Newtonian compound, unthinkable then, or a one-piece mesh, with non-visible reinforcements instead of the classic leather straps and reinforcements. Yes, both aesthetically and technologically, it has evolved, a lot. This is about the technical solutions that we can find in this shoe to improve the running experience.
Without a doubt, the midsole is the part of the shoe where Brooks Glycerin 18 plays the beans. The "daily training shoe" is not a label that is put on the shoes to put them in one basket or another. A daily training shoe must be able to withstand the training loads, intensive or not, of any runner ... And also, the next day: more of the same ... And the other ... Those who use this type of model not only have to save each session, but their muscles and joints have to come out alive, so that the next day they are prepared for a new session, if that is the will of the user.
That is why the Glycerin 18 midsole is so careful. The non-Newtonian material you referred to in the introduction is DNA and the variant used here is DNA LOFT.
To explain what DNA is, you have to put running and how a midsole behaves in context. When it hits the ground, it (the ground) does not flinch, and all the force and vibration caused by that impact goes to the body, starting with the feet, leg, the joints involved and from there upwards ...
The job of a midsole is to be able to absorb a good part of that impact and that its effects are as less harmful as possible (and more so considering that in a 10k, for example, we are going to hit, very approximately, five thousand times with each foot). Well, all the midsoles with better or worse performance do that ... The grace of the DNA used in Glycerin 18 is that it is capable of behaving differently depending on the gait that the person wearing these shoes is wearing.
And it is that DNA is a non-Newtonian polymer that will cushion in a softer and more progressive way the slower the march ... On the other hand, if whoever uses them wants to go faster (and therefore the hitting is somewhat more violent), then the DNA material is going to behave more firmly, so that the response is more in line with a more cheerful type of gait, in terms of rhythm speaking.
The LOFT variant is a type of finish that Brooks has printed on the DNA used in this case. LOFT gives it an even softer touch, since it is not for nothing that it is a model designed to accumulate sessions and kilometers, hence comfort is also important.
The drop is still the same used in Glycerin 17 and it is 10mm.
The Brooks Glycerin 18 outsole follows the lines of its predecessor. In it, it is easy to distinguish that the part of the forefoot is quite wide, which gives it stability when falling with everything, in full transition of the footprint. On the other hand, the heel area is shaped like a horseshoe and in this case favors entry with any type of footprint.
The forefoot design shows shallow but wide studs with a lot of contact surface. Among them various transverse grooves make the flexibility very good. Up to seven grooves, five of them deep to the midsole, attest that flexibility is important in this model.
The back part, the one with that horseshoe shape, is divided in two. It is very easy to distinguish the outer piece, of another color, which is reserved for the outer part of the heel. This area is the one that suffers the most from the entire sole, so here the rubber is much more resistant. Brooks painting it in another color is for no other reason than to distinguish the technical detail.
The upper or upper cut of this Brooks Glycerin 18 shows a shoe without fanfare and that discreetly integrates key elements such as, for example, those related to support. It could be said that there are, heel aside, two areas with different and clearly differentiated functions in the mesh: the front and both sides.
The front part uses an open and highly breathable mesh, with the ability to stretch and deform. It is correct: in the fingers we need a lot of ventilation and also mobility and here Brooks has seen it clearly with this Glycerin and also thinking that, for long runs or high-mileage races, the fingers suffer just enough.
What we see on both sides of the Glycerin 18, and taking into account that here, the most important thing is the support and in all phases of the tread, it is a mesh with fewer openings. This is to make it stronger and resistant to the forces that pull it when the foot swings. In addition, the dots (rather pentagons) that are glued on the outside of the mesh are not an aesthetic issue, but are pieces of PU that will further reinforce this area. Since nothing is casual, it is the 3D Fit Print technology that Brooks uses in some of its high-end models.
The laces are flat and are passed through six eyelets leaving an extra free one at the ankle for those who want more tightening here. They also do it through the reed pin, although it is not necessary since it is attached to the body of the Glycerin, so it will not move while you cum with them.
The bowl is very padded, as well as the thick insole: 5mm and very spongy to increase comfort. The shoe is finished in the heel area with a buttress that stabilizes the ankle and incorporates a reflective strip so that whoever uses it is visible in low light conditions.
Brooks Glycerin 18 continues to be a benchmark in everyday training shoes. Its careful and soft cushioning, thanks to the DNA LOFT compound, also makes it one of the best options if you are looking for comfort of use during all types of mileage.
The weight of Glycerin is 300gr in the men's finish and 268gr in the women's one. And since we are talking about weight, it is valid especially for runners of medium, high or very high weight if it is the case, since it is prepared for it.
The sole combines a resistant rubber in the heel area and more adherent throughout the front, while its design favors flexibility. Everything is combined with a comfortable, ventilated and flexible upper in the toe area and stronger in the midfoot, for support.
There are quite a few runners (the ones who do a lot of shoot-based workouts, or who like to be comfortable in races, especially the longer they are), that don't come off best-selling daily training models like Nike Air Zoom Vomero or ASICS Gel Nimbus. But that happens to them, in part too, because they don't try others like this Brooks Glycerin, who most likely don't know that they would be pleasantly surprised.
The official price of Brooks Glycerin 18 is € 170.
