 in style BLUE / ICY PINK / ROSE


The Brooks Glycerin GTS 21 provides you with miles and miles of softness and stability.

This plush shoe is optimized for your comfort by being lightweight, responsive, durable and cushioned. Whether you are on your feet all day for work, enjoying a daily walk or training for a marathon, the Brooks Glycerin GTS 21 gives you a stable and plush experience.

Brooks uses its GuideRail® technology to support your body in its natural motion path while keeping excess motion in check, ideal for those with flexible arches or who overpronate and like a bit of extra stability.


  • Upper - A new, engineered warp knit upper improves the fit and feel on your foot. It is breathable and flexible, while still being soft and secure.
  • Midsole - the new nitrogen-infused DNA LOFT v3 is added to the Glycerin GTS and there is even more of it to give you a plush, durable and responsive ride. A broad platform makes sure you have smooth heel-to-toe transitions.
  • Stability - Brooks’ GuideRail® holistic support system supports your body in its natural motion path while keeping excess movement in check, similar to bumpers on a bowling alley.
  • Outsole - New RoadTrack rubber on the outsole is lightweight, durable and includes recycled silica.

Great walking shoe

Great walking shoe very supportive and comfortable. Loved the pink/blue colors on the shoes and find they help to keep my feet in good shape for all my walking. Cushioned on the insole and plenty of good construction on the entire shoe.

I am really struggling with this particular sneaker. Hard surface inside next to right toe really rubs. Same for the top of the shoes pressing hard on the top of the foot. This is my 4 or 5th pair of Brooks and have ordered the same size everytime. 9.5 super painful to wear. So disappointing compared to the other Brooks that I have loved.

My wife loves these..

Better shoelaces and really comfortable!

I loved the Glycerin GTS 20 and was so excited to get these. I think they might be better than the 20's. The cushioning is very similar to the 20's but feels slightly better due to the change in shape. The toe box feels a smidge wider and is good. And the best part is they have better shoelaces! I'm looking forward to seeing what additional colors come out in the next few months.
