Even though the medial midsole is slightly softer, its solid sidewall design provides greater stability than the grooved lateral side. If you are running up to a half marathon we would advise going up a half a size to your normal shoe size. This creates a sort of softness to the landing with enough resilience that it seems firm into toe-off.

Most of the elite were wearing Alphafly or carbon-plated technology, meant for max speed and not daily training. It's stuffed with a light foam that compresses for a natural fit, so it's flush with the rest of the upper and won't disproportionately press down into the top of your foot. GuideRails Holistic Support System: They’ve shifted the focus beyond the feet to the most injury-prone part of a runner’s body: the knees.

The Brooks Adrenaline GTS 20 Women’s Running Shoe has changed focus from the feet to the knees which can be one of the most injury-prone parts of the body when running. It looks better on-foot than I expected, and I’ve actually been choosing it for some casual wear in addition to my runs. But, rather, the stability foam should gently guide the foot into holding the right position, leading to good overall alignment (hence the "Guide Rails" system moving to all-around support rather than just putting foam on the inside arch of the shoe).

All of the above combine to produce a shoe that thankfully is not overly-plush/sinking cushion, and an extremely fun ride. The word “holistic” derives from the Greek holos meaning “whole”; the metaphorical usage means a whole that is greater than the sum of its parts—which is the perfect description for Adrenaline 20 (explained below). The Glycerin GTS 20 faithfully follows the Glycerin GTS 19 which combined the stable, smooth-ride tradition of Brooks Transcend with the brand’s long-running Glycerin name and more-trimmed design. These material changes make a difference in the overall weight, so the new GTS is lighter by half an ounce. Truth be told, I haven’t run longer in Adrenaline, but the lack of hot spots by 10 miles gives me a fair assessment that the shoe fit and support will hold up for higher mileage.

Brooks has heightened its user-friendliness with options to choose a Classic or StealthFit upper on either Glycerin or Glycerin GTS, though with more color options in the neutral shoe. Their extremely large selection of products guarantees that you’ll find what you need every single time.

The Classic fit option combines a standard, durable, double-layer engineered mesh upper with traditional lacing and a moderately-plush tongue. New, integrated GuideRails support is smoother than ever while just-right cushioning softens every step.Thankfully they felt supportive enough and did not give me any pain or soreness in my feet as I usually get after using lightweight shoes for longer sessions. If you are a diverse distance runner with overpronation looking for a supportive daily trainer and walking shoe combo and want a very versatile shoe that feels great all day, the Brooks Adrenaline GTS 20 is for you. A quick scan of reactions to the last model reveals no surprises: love it or hate it, change rocks our world. We've shifted our focus beyond the feet to the most injury-prone part of a runner's body: the knees.

Since I already knew about the two layers of cushioning and the stability technology, I was anticipating a less than ideal assist for my fast miles.

Stability, cushioning, responsiveness…it all sounds like the best way to describe a good running shoe, but what do these terms really mean? I could still feel the terrain and pavement well at race pace, which is part of the joy of running for me. These Rails, designed with the idea of bowling bumpers in mind, keep my knees in alignment because they gently direct off-kilter foot motion back into forward momentum.
