DNA Midsole

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

    Loyal Defyance runner

    2017/05/22 | Houston, TX |

    I felt I had to defend this shoe. I've been running in the Defyance for probably 10 years now (as a former Division I runner and now recreationally). I wear a size 9 in street shoes, and typically size up to a 9.5 in running shoes to accommodate my inserts and just because I like a roomy toe box for running. My first pair of Defyance 9's I purchased my typical 9.5, then I sized up to a size 10 on my next pair because they do seem to run a bit smaller than previous Defyances. Not a deal breaker at all, and that is the only issue I've had with these shoes. I encourage you try them out for yourself and don't just listen to the negative reviews. Everyone's feet are different.

    Yes, I would recommend this!

    Defyance 9 is my first pair!

    2017/04/18 | Charlotte, NC |

    I feel the need to defend this shoe! As it is my first pair of Brooks shoes, I can't compare these to previous models, but I have been very happy! I do have narrow feet, so maybe some of the complaints wouldn't impact me. I didn't know I needed a dyad--didn't even know what that meant--but have loved feeling that my feet and ankles are well-supported for running or walking. My only complaint is that I am wearing holes in the toes very quickly--much more quickly than in cheaper shoes.

    It is the end of the road for me and the Defyance

    2017/03/26 | florida |

    I Have been wearing Brooks Defyance since the Defyance 3. The Defyance 5 was my all time favorite. I bought 7 pairs of the 5 and am now unfortunately on my last pair. Defyance 5 had perfect cushioning, yet enough support with just the right amount of flexibility to protect the balls of my feet while allowing for a smooth stride. I sorely miss the gel and find the new foam to be too firm. I tried the 6 and kept it. Tried the 7 which was unattractive and increased supination, so I returned it. I kept the 8s out of desperation, although I found them to be not as supportive or protective of the forefoot. The 9s were so bad they caused ball of foot pain after wearing around my house for 35 minutes. Unfortunately, I am now looking to other shoe brands for a more cushioned, supportive shoe with a roomy toe box. I have found all Brooks shoes including the Dyad to have become firmer, offer less forefoot protection and smaller all around.

    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.
