    It rolled smooth enough, but it never felt to me to be the smoothest racing flat I've ever had.

    I really cannot say enough good things about the Brooks Racer ST.  As I said they are a personal favorite.  If nothing else take a look and try them on.  They are well worth your time.

    Before this year, the Brooks Racer ST 5 was my go-to shoe for any race distance. It is lightweight, looks great, and provides a good amount of support. I would definitely recommend this shoe if you are looking for a racing and speed work shoe.

    This shoe is so smooth and fast you will completely forget about what's going on at your feet.

  • 85 / 100 | The Running Centre | Level 3 expert

    The ST 5 is perfect for the runner searching for a performance footwear option for longer distance racing (>12km) or an introductory shoe for those currently conditioned to volume or lightweight trainers.

    When I first put the ST’s on, I was thoroughly impressed. The shoe fit thin and narrow which allowed them to stay snug around the sides and top of my foot.

  • Brook’s lightweight trainer in the Racer ST 5 continues its trademark of exceptional performance by offering a few tweaks in its upper and outsole. The upper has rounder and bigger mesh all throughout, including the heel and the tongue. Nothing makes a shoe more breathable than an update like this.
  • Brooks also removed the plastic material near the eyelets and replaced it with a softer suede material. The new material is seen as one way of improving the comfort and adaptability of the upper.
  • Runners will find the new heel loop very convenient when putting on or taking off the shoe.
  • The outsole continues to be full-contact and features a deeper vertical flex groove that runs from the midfoot to the forefoot.

The fit and sizing of this latest version of the Racer ST 5 are standard like the past versions of this line. Average fit in the heel, the midfoot, and the forefoot are available for those who want to run in a very versatile shoe. Brooks offers the unisex version of this shoe with sizes ranging from 5 to 14 with a medium width.


The HPR Green technology, which is exclusive to Brooks, features shallow lugs made of a hard rubber compound that is skid-resistant and enhances traction. Also, by using the Stable Pod Configuration of the rubber, the runner has better stability and more efficient strike from the heel to the forefoot. A new and deeper flex groove from the midfoot to the forefoot enhances transition and flexibility in this shoe.


Brooks packs the midsole of the Racer ST 5 with numerous high-end technologies. The Hydroflow ST is a cushioning gel filled with viscous fluid that adapts to the running style of the wearer. It is located in the heel of the shoe, specifically in between the BioMoGo midsole and the Stable Pod Configuration rubber. The material is exceptional in terms of protection against landing impact, shock attenuation and additional stability in the heel. BioMoGo DNA covers the entire length of the shoe as well.  This midsole technology is also featured in the popular Brooks stability running shoe, the Ravenna 10.  The BioMoGo DNA uses a sophisticated technology that provides cushioning only where and when the runner needs it. Brooks calls it adaptive cushioning at its best. This midsole foam provides more cushioning than standard EVA and delivers twice as much energy return.

The stability of the shoe comes in the form of a dual-density foam called the DRB or diagonal rollbar. It effectively supports the medial side of the shoe to curb overpronation. There is also a plastic shank known as the DRB Accel. This TPU insert provides midfoot torsional rigidity and makes transitions smoother.


Occupying a major part of the upper is the Element Mesh. Besides being stretchy and extremely adaptive, it makes the shoe really breathable. For support and structure, Brooks uses microfiber and synthetic overlays. A moisture-wicking interior begins with the Ortholite Sockliner. It has anti-microbial and anti-odor properties for a healthy and very comfortable inner shoe.
