The Dynafit Ultra 100 shoe is built for runners with high expectations. That is, high miles, high cushion, high comfort, and high versatility. There’s no way around it - a century run involves a lot of constant abuse so you’re going to need as much cushion and support as you can get without it ruining your stride. The Dynafit engineers worked their magic to create the ultimate ultra shoe catered for those of us who find Zen in racking up dozens of miles in one go. While they were at it, they figured running those lengths with a rock in your shoe might just qualify for the most obnoxious possibility, so they incorporated the invisible lacing system to keep out unwanted debris! Going for a long run? Don't forget to grab your Dynafit Ultra 100's before you go get lost in the woods.

SkyRun Fit Tip - We suggest sizing up the Ultra 100's by one whole US size for the proper length.

  • Built for any condition so you won't need to check the weather before hitting the trail.
  • Maximum cushion will keep your body feeling fresh mile after mile.
  • Pomoca Gliding Path allows for a natural stride with optimal push-off for excellent efficiency.
  • Invisible Lacing system keeps your laces in place and debris out of your shoes.

This has been my go-to shoe this past spring through summer, and for the most part, has replaced my prized La Sportiva Mutants (I've owned six pairs) for less technical and scrambling terrain and for just an overall lighter package. For my rather narrow and low volume foot, they fit great but I ended up going a full size up for a proper fit. These shoes provide great cushion for longer miles and unlike other high cushion shoes I've worn they don't feel clunky, super unstable or like you're running in clown shoes. I was a bit dubious after having running basically solely in very aggressive lugged shoes that these wouldn't hold up to the challenge but after a number of days on the West Face of Grandeur, Superior, and around the trails at Alta I've been humbly surprised at the traction. While the Ultra 100s won't entirely replace my need for the Mutants, I think Dynafit has done an excellent job with this shoe and I look forward to putting down many more miles in these shoes to come.

If I could only have one shoe, these would be the ones! The Ultra design provides enough cushion and comfort for big days, but they're light and snappy enough for spadework and daily runs. I dig the Pomoca rubber outsole. They're grippy and durable and not over-the-top aggressive. I put 450 miles on these before grabbing a new pair (90% on trail). At this point, the outer started to blow out, but the tread was still in great condition.

My recommendation is to go up one full US size. With that in mind, fit is great for a medium-wide foot.

Great shoe if you can get the fit right. I’m normally a 8 or 8.5 but ended up in a size 9 and I’m not sure I even went big enough. This shoe has great arch support, fantastic traction, and great cushioning for long distance. My uncle and hiked the Enchantments in Washington last year and there were things I loved about this shoe and things that didn’t go so well—most likely due to fit. Things I liked: The cushion wouldn’t give out and it didn’t make the shoe bouncy and unstable. Traction is great, there’s a lot of steep scrambly terrain in the enchantments and these didn’t give me any trouble. Things I didn’t like: the laces are very thin and cheap feeling; I always feel like they are going to snap when lacing them up. If they ever do snap I have no idea how I’m going to lace them up again without cutting off the gaiter. Maybe I could pay one of my toddlers with gummy bears to get access to their tiny hands... Fit is odd. I need more time in these this summer to figure out if a 9.5 is the ticket or not. My pinky toes got irritated on my 20+ hike and at the end of the day padding at the collar was poking me around my ankles. I’ll give them another go before trying another size.
