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!

Ugly is only skin deep. These are soooooo comfy!


Comfortable from the second I put them on. Wore them all day. Had been wearing altra's but the zero drop was a bit too much for me. The 5mm drop is just enough. They do gap a bit at the ankle...a function of the depth of the shoe? And boy are they UGLY but who cares if my feet dont hurt. Perhaps I should not have gotten black. True to size but can you work on the colors and style details? I'm not an old man!

You NEED these shoes.


These are the best shoes ever!!! I have had pain in my big toe knuckle for about a year now. Podiatrist couldn't figure out what was causing the pain or what was actually wrong with my foot. The only thing I have figured out is that I need a wide toe box like Topo's. I run completely pain free in these shoes. I was worried that the lower heel-to-toe drop (5mm - I am used to running in 10-12mm) would cause problems for my Achilles/calves but no problems so far and I have about 225 miles on these shoes. Do yourself a favor and buy these shoes.

*My one complaint is color choices. PLEASE add some new colors Topo!
