A great shoe, need different colors.


Not feeling these new color choices, will you be offering more soon? I need this shoe STAT, I'm on my feet 13-14 hours at a time. I purchased the old model and they were great except that the upper mesh wore out after about 3-4 months of heavy use. Thank you!



This shoe. I went through two pair of the originals in the past year, mostly because the mesh couldn't hold up to my toes, and they poked through. This new shoe is amazing; it has the mesh similar to the Fly-Lyte 2, which proved much more durable (my 2nd favorite shoe), and the cushioning is just a tad bit nicer. Got them yesterday and did 6 miles this morning and felt amazing. These are much improved and I am looking forward to many miles in them!

Plenty of spring for that kick with the right cushion.


This shoe immediately became my favorite! I found the Ultrafly 2 to have more of a snug fit in the heel than the original in addition to more of a sleeker toe area that gives more of a push, spring than the original did while maintaining the wide toe box. The shoe is flexible, lightweight with plenty of cushion without a clunky feel. My 1st run in these shoes was an easy paced 3 mile jog and my 2nd run was a 10K race. Going into the race I wasn’t sure how the push off would be but the shoes did not disappoint. They performed well no blisters, no hotspots and ease of a push-off when I was ready to pick up the pace. After 1 week I ordered a second pair in a different color.

Love at first walk


I purchased the original Ultrafly for walking on pavement. Love the support they give my arches. But after a month I started to get hole in mesh from toe. I put a piece of moleskin inside to protect and make them last. I see that others have had same problem. Would like to know if the 2 has the same solid arch support.

*Topo note: The Ultrafly 2 has the same platform as the original Ultrafly, but features an updated mesh upper that is more durable.*

Must have for long nursing shifts!


Ultimately I would recommend this shoe. It’s very comfortable and supportive right out of the box. I wear them on days I work 12+ hours and they keep my feet happy. I don’t like the design and color choice as much as the previous model. I do hope they last longer and my toes won’t pole thru, but I. Can’t attest to the durability yet.

The Ultrafly 2 saved my running career


I have been suffering with foot calf issues for over a year and have been on an endless shoe hunt. I've tried zero drop, higher drop, neutral shoes, stability shoes. Nothing I tried was working and I was about to give up on running. A friend of a friend swore by his Topos. I've had mine for a couple of months and love them. My calf is much better and more importantly I don't have any foot pain. I like the minimal drop on this shoe. The real selling point for me is the changer. The fit is comfortable and there is plenty of room in the toe box. I have finally found my shoe!! Thank you Topo!
