What is it?

Brooks DNA is an innovative and uniquely adaptive cushioning system. By adapting to your specific weight, pace, gait and running surface, DNA offers customized cushioning and adds a spring to your step.

Traditional cushioning takes a one-size-fits-all approach, but we know that each runner is different. Brooks DNA was developed to continuously tailor the level of cushioning to your specific needs – even as they change during the run.

How does it work?

Brooks DNA is made up of a non-Newtonian material or more simply put, a material that adapts to the specific force you apply to it. Part of the brilliance is that this compound was engineered to perform at the molecular level (picture millions of resilient 'nanosprings').

If you looked at Brooks DNA through a microscope, you'd see that it's made up of individual molecules connected in strands. These strands (which form chains) react to the amount of force placed on the foot, dispersing pressure and providing resiliency. Bottom line of this physics lesson: You get tailored cushioning that reacts to your specific weight, pace, gait, movement and running environment – "made-for-me" cushioning vs. "one size fits all."

And, as with all good technology, we’ve taken it a step further (two steps actually):

  • BioMoGo DNA is DNA technology blended with the BioMoGo midsole to provide adaptive cushioning throughout the midsole vs. just in the heel and forefoot.
  • BioMoGo DNA midsole includes an organic, non-toxic additive that biodegrades the midsole 50 times faster than traditional EVA when it comes into contact with anaerobic landfill microbes (otherwise known as active, enclosed landfills).
  • 30% more cushioning than standard midsole materials (gel or EVA)
  • Twice as much energy return for more pep in your step
  • Great performance no matter your weight or running pace
  • Smoother transition from heel to toe

    Not even close to the 8s

    2017/01/03 | The Woodlands, TX |

    I found that cushioned shoes became too cushioned and aggravated both my metatarsal joints and PF. A store gave me the Defyance 8 which was the answer to all my prayers. My running was great, and my feet did not hurt, straight out of the box. They were perfection, but as shoes do, they wear out. I could not find another 8 and my local stores stopped carrying the 9s because of negative reviews. I gave them a chance. I should have listened. After a 6.5 mile run, the balls of my feet are screaming and every toe felt like it was on fire or numb. I liked this line because there was a little cushion but not too much; these felt like they had zero. The Ghosts were too soft, the Glycerines were way too soft. Now I have to revert to my worn out 8s.

    Very bad shoe

    2016/12/01 | FL |

    I run 3 times a week! Always had Brooks shoes nut this is the worst product ever made by Brooks! The nose of the shoe bows and that causes blisters on the top of your feet.

    Love Defyance, Hate the 9!

    2016/11/01 | boston, ma |

    LOVE the Defyance line. They are my favorite as I have many pairs over the years. I thought it was just me when I got the 9's that they changed and I continued to use my older 8's. I've now seen that many people feel this way too. I hate the new version as they are not the same as before. The older versions were much better with more spring. These are harder to run in for me.

    Yes, I would recommend this!

    I would buy this product again

    2016/10/19 | Indianapolis, IN |

    Specifically bought the product for running, and maybe to wear casually 1-2x/week. I only run 6-10 miles/week and unfortunately I'm getting shin splints, however this could be d/t my weak ankles, poor arches, flat feet etc. The product is super comfortable to wear and affordable.

    Yes, I would recommend this!

    Way too tight at toe box

    2016/08/31 | Portland, OR |

    What were you thinking with the redesign of this shoe, Brooks? I have bought this model for years and years---every time I need a new running shoe, I just buy the new version of the Defyance and it always works great. Went running with my new pair this morning and the toe box was painfully small and narrow. I felt like I was wearing dress shoes/high heels with the way my toes were scrunched. Held the shoe up against my last pair and sure enough, this model is noticeably smaller and narrower at the toe. Who are you designing shoes for with this pointy-toed disaster? I am extremely, extremely disappointed.

    What has happened to Brooks!?!

    2016/08/22 | Michigan |

    What has happened to Brooks!?! My two or three all time favorite, can depend on, go to shoes were made by Brooks for years. For some reason they decided to make sweeping changes to them and I agree with the other reviews - the new ones just do not make the grade. They say they fixed the sizing issues in the Adrenaline 15 - it is still too narrow in the ball of the foot and the new application of the trim around the toe box means it now breaks on your big and pinkie toes. And now the Defyance is completely different. I'm hoping they change the trim on the adrenaline back to where it previously was and not even sure what they can do to get the Defyance back in shape! It's a shame. Used to be a go to company. Now, not so much.

    Unhappy with changes from previous models

    2016/08/10 | Boston, MA |

    I have had many previous models of the Defyance, and all of them I have been very happy with. I wear orthotics, so I need a stiff neutral sneaker to maintain my alignment while running, and this has been the ONLY shoe that has given me proper support. Unfortunately the Defyance 9 update has been a huge disappointment. It feels clunkier and less cushioned than the 8, and feels wider in the ball of the foot. I'm so disappointed in this model that I started another epic search for another appropriate sneaker, and will likely have to switch brands. The Defyance 8 was really onto something great, the Defyance 9 has been a step in the wrong direction. Hopefully the 10 will be something more similar to the 8

    Not as good as previous versions

    2016/07/16 | Boston |

    I switched from the Adrenaline to the Defyance several years ago, I think with the Defyance 3 or 4. 5 and 6 were great, I did not have a pair of the 7. The 8 took some getting used--much longer and narrower than the 6, had to go down a size--but in the end I loved them. The Defyance 9 is a different story. I've been wearing them for about 6 months now and I still don't like them. I can't pin point what is wrong with them. They seem like they are a lot of shoe. They don't feel as neutral or as natural as the 8. There's like extra room in the toe but the toe is too pointy. And this might be stupid, but the laces are super long and they shredded. The colors of the 8 were awesome, but I'm almost embarrassed to wear the 9. Overall they seem like a very old fashioned running shoe in both look and feel. I have to get a new pair and I don't really want to buy another pair of the Defyance 9, but I also don't want to have to go on an epic trial and error search for a new shoe. Please go back to something like the 8 when you design the 10.

    Fabric ripped in less than 300 miles.

    2016/05/21 | Bremerton, WA |

    I have ran in the Defiance's from version 3. I have LOVED them. Unfortunately with the revamp of the 9's they feel very narrow, and have I worn through holes in the fabric with less than 300 miles on them. I have never had holes in my shoes even with 450-500 miles on them. This new version is not the same shoe, and leaves me really questioning what to go with next, as I have worn Defiance's for the last 6 years.
