Ultraflys rock!


The Ultraflys have quickly become my go-to mid to long distance road shoe. It has enough cushion to hold up for 20+ miles, durable (have put 500+ miles on multiple pairs, and super comfy. I do wish it was slightly lighter though. Note that I am a Topo Ambassador and was hoping for a shoe with more cushion, so glad they responded with one.

Comfortable, Durable shoe


These exceeded my expectations!

First off I don't consider myself a "road runner", but I have put in many training miles, two 50 mile endurance events, and a 37 mile solo run in my single pair of Ultrafly. The cumulative total is close 700 miles and I still find myself grabbing them for anything on road more than about 8 miles!

I have a couple tiny holes near the big toe and the mid foot cushion is (understandably) less than when purchased. The tread is also close to smooth under the big toe.

Another important point for me, as a runner with bunions, is the wide toe box. Anything too tight at the toes becomes excruciating. These fit securely around the mid foot and ankle while allowing my toes the space they need.

Looking forward to many more miles with Topo and honored to have been chosen for the Topo ambassador team!

Comfortable. Dependable. Versatile.


Love the Ultrafly! Have worn them successfully in road marathons, 24 hour races and even a trail 100 Miler in the UK.

The Ultrafly is extremely cushioned, yet super-stable. Up front the traditional roomy Topo toe box provides tons of space for your toes to spread out, but the fit through the midfoot and heel is snug enough so your feet don't slide around.

I wish the Ultrafly were a little lighter, and perhaps $10 cheaper, but for such a dependable shoe you really can't go wrong.

Note: if you're anything like me, it may take 20-30 miles to "break-in" the shoes, but once they're broken in you can look forward to hundreds of fun, cushioned miles.
