Give your PR a boost.

Your former PR doesn't stand a chance the moment that you lace up the Adidas Women's Ultraboost X Running Shoe. Delivering unprecedented energy return, the Ultraboost features Adidas' boost midsole material, which enhances the swiftness of your transitions, attenuates shock, and bolsters your comfort underfoot. The shoe also features a floating arch that molds to the contours of your foot, while the Primeknit upper hugs, adapts, and flexes with your stride, preventing hot spots and chafing that sometimes occurs with ill-fitting shoes. Additionally, the Continental Rubber outsole maintains subtle, yet substantial traction when you need it most, which will come in handy considering you're kicking up dust faster than oxygen feeds a flame.

  • Take down your old PR with this running shoe
  • Neutral design and 10mm drop propel you through transitions
  • Primeknit upper breathes and provides a personalized fit
  • Floating arch conforms to the shape of your individual foot
  • Boost midsole attenuates shock and enhances energy return
  • Continental Rubber promotes traction even on wet surfaces
  • Yarns in the shoe made from recycled ocean waste

Do not regret

    Only been wearing these for a day, but they fit perfect. I can see why people say they are a bit narrow, but I think that is okay and they will break in.

    Decent Running Shoes

    • Familiarity: I gave it as a gift but have feedback to share

    Gave these to my sister for the holidays and she had this to say:
    "These are super comfy running shoes! But not gonna lie, I'm going back to Nike after this. These feel a bit wide, but are also not worth the price tag. And this is obviously a matter of taste, but they just don't look as good as Nike frees or reacts."

    Run a little snug

    • Familiarity: I returned this product before using it

    Big fan of adidas and the ultraboost technology. I have the original Ultraboost in a 7 and they fit perfect, these however ran a little small for my foot but I think a 7.5 would be too large. From toe to heel I'm 9.5 inches with 3.5 inches at the ball.

    My Favorite Shoe EVER

    • Familiarity: I've used it several times

    Throw away all your old shoes and buy these NOW... they are amazing!!! I usually wear an 8.5 in shoes but have to get an 8 in these.

    Great Shoe

    • Familiarity: I've used it several times

    These Adidas' are super light weight and give great support while running. I love how they hug the ankle with the elastic frame. Makes them feel much more stable and secure. Plus they are super cute, so you can also just throw them on with a pair of jeans and a t-shirt and you're good to go!

    Great running shoe . Very comfortable,stylish a good everyday shoe.

    Nike who?

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    Adidas has definitely stepped up their game lately and these shoes are walking proof. My wife snagged a pair and they have hardly left her feet since. Durable, comfortable and steezy as hell.

    Light Shoe with Good Support

    • Familiarity: I've used it several times
    • Fit: True to size

    Very Light running shoe with great stability. I bought these for my sister and she says the cushioning on the mid sole is unlike anything she has ever run on before. I also spoke to the addidas rep and she said that the midsole on these shoes are designed to outlast standard foam and last for more miles. Haven't quite put this claim to the test but will be reporting back to see how they hold up over time.
