Brooks Glycerin GTS 21 Introduction
The Glycerin GTS 21 follows the Glycerin GTS 20 and continues to supply a secure experience with a really clean transition. Glycerin GTS is the steadiness model of Brooks’ Glycerin, which suggests it’s the similar shoe however with the added characteristic of GuideRails® to assist information the foot by way of common pronation.
Glycerin GTS is probably the most plush stability providing from Brooks, becoming a member of the Launch GTS with its pace focus and Adrenaline GTS which sits between the 2 in cushion.
This shoe retails at $160 USD, the identical as final 12 months and because the Transcend 4, 5, 6 and seven, the earlier title for Brooks’ most plush stability shoe (the fee was $10 decrease for the primary 12 months when the title and design switched to “Glycerin GTS 19”).
The listed weight stays at 10.5 oz. (297.7 g.) in a US M9 and drops barely to 9.2 oz. (260.8 g.) in a US W7; the StealthFit model with a compression knit higher is a few half ounce lighter.
Brooks permits runners to decide on their preferences with decisions for “StealthFit” or “Basic” for the higher and “Impartial” (Glycerin) or “Assist” (Glycering GTS) for the midsole, common or vast width.
Glycerin GTS competes with Saucony Omni, New Stability Vongo, and ASICS Gel-Kayano for top-end stability choices.
Total, I like to recommend Glycerin 21 GTS over the Saucony Omni 22 with two exceptions:
1) I take the sock liner out of Omni to place in Glycerin; it’s thicker and gives extra arch assist;
2) You’ll in all probability desire Omni in case you have a slim foot. I stayed with the half-size smaller in Omni than Glycerin as a result of although I’d desire a barely wider toe, the size was true to dimension. Sizing up would have made it actually lengthy.
Select Vongo if you need the additional stiffness and spring of a nylon-plated shoe and Glycerin GTS in case your foot will get uncomfortable sporting a plated shoe.
Brooks Glycerin GTS 21 First Impressions
Unboxing Glycerin GTS 21, I cherished the slick, clear model and appeared ahead to stepping onto this plush, engaging mannequin.
It didn’t disappoint in really feel underfoot, however I knew straight away that I would want to dimension up a half dimension. True to the .2 ouncesdrop within the listed weights (for girls), the 21 in my dimension 10 weighed the identical as final 12 months’s dimension 9.5.
The primary run felt clean, and this continued by way of my testing interval (70 miles).
Brooks Glycerin GTS 21 Higher
The Basic match possibility combines a sturdy, double-layer engineered mesh higher with conventional lacing and a moderately-plush tongue, this 12 months constituted of over 61% recycled materials.
The next, extra stable heel counter this mannequin is a pleasant shock; padding across the ankle is average. My heel didn’t slip, and my foot felt supported.
The shoe has higher breathability and a extra comfy match that doesn’t require as lengthy of a break in as within the 20.
The StealthFit higher possibility, accessible in each Glycerin and Glycerin GTS, permits for much more stretch, like Nike’s Flyknit of their React Infinity Run FK 2.
My least favourite a part of the shoe is the sock liner. It’s common, however for a $160 shoe I might hope for one thing extra sturdy and supportive underneath the arch, like I discovered within the ($30 cheaper) Omni 13. After about 40 miles of testing the Glycerin GTS sock liner felt flat. I prefer to put the Omni liner into the Glycerin GTS for a greater really feel underfoot contained in the shoe.
The look is engaging and alluring, with a less-busy sample than the 20 and a wide range of colorways to select from.
Brooks Glycerin GTS 21 Sole Unit
The midsole gives a wonderful experience. As soon as once more product of Brooks’ nitrogen-infused DNA LOFT v3 materials, it gives a softer touchdown than a conventional EVA mix and a lighter experience than the model’s DNA LOFT.
This nitrogen method brings a singular really feel: tender but resilient — not plush, however comfy. The experience is mild and ethereal, with a rocker really feel underfoot and fast transition into toe-off. The drop is 10 mm.
The GuideRails® stay largely unchanged since their 2019 revamp in Transcend 6. This distinctive method to counter extra movement and alleviate stress on knees and hips works along with the higher’s heel counter to rein in motion.
The GuideRails® encompass the midsole extending as much as border the shoe to offer assist if wanted. If not, they don’t seem to be noticeable. The GuideRails® additionally assist assist the arch of the shoe to direct foot movement ahead somewhat than rotating too far inward.
Once more this 12 months the skinny, carbon-rubber outsole would be the first a part of the shoe to proof put on. A further flex groove simply earlier than toe-off exposes the midsole, and after 70 miles on my sneakers I can already see it beginning to fray.
On the optimistic facet, the outsole covers extra of the lateral midfoot.
Brooks Glycerin GTS 21 Conclusions
It is a exceptional shoe that’s enjoyable to run in. The principle factor preserving me from giving it 5 stars is the “meh” sock liner.
Sock liner apart, attempt Glycerin GTS 21 for the very best in cushion, stability, and higher assist.
Earlier than shopping for, first verify to see in case you have heavy put on patterns underneath the medial toe field in your earlier sneakers.
The brand new flex groove underneath Glycerin GTS’s huge toe exposes the midsole, and it may be a warning so that you can attempt a distinct mannequin to keep away from untimely put on.
