Deep in their research labs, the wizards at Dynafit brooded over how to conjure up the best race-ready, ultra-distance slaying machine out of the capable Ultra 100, and the Dynafit Ultra DNA was born. Adding Litebase to Vibram's durable Megagrip outsole takes precious grams off the overall weight but sacrifices none of the sure grip. Dynafit's energetic Speed+ midsole, signature heel-preloader, and underfoot Rockshield are sandwiched between the outsole and the upper, which helps with foot fatigue and adds cushioning. Additionally, this combination provides incredible energy return and a surprising amount of trail feel, making the long miles ahead seem trivial. The quick draining and breathable upper is affixed with double speed lacing because seconds are precious, and getting that just right fit is crucial. If you subscribe to long, slow distances and get your speed work in, then the Ultra DNA is the perfect choice for race day.

SkyRun Fit Tip - We recommend sizing up one-half to one whole US size for the best fit.

  • With the introduction of the Speed+ midsole, users can now enjoy superb cushioning and increased energy return.
  • Vibram Litebase and Megagrip outsole shaves weight and provides excellent traction on most surfaces, wet or dry.
  • The double-speed lacing system makes adjusting the fit for a long descent hassle-free, ensuring a snug and secure fit.
  • The underfoot Rockshield fights the good battle with all the sharp, pointy bits.

Question from Zachary Garner
I wear size 45.5 in la sportiva. Would 45.5 in this shoe be a similar fit?
Answer from Jeremy L
Hi Zachary. That's a tough question without knowing what Sportiva shoe and how it fits. If you fill out the shoe fitter, I bet we can get you dialed in.
