Ultrafly 3
Product Overview
Topo Athletic's Ultrafly 3 delivers a smooth and comfortable ride with light guidance for daily training. The moderately cushioned platform features a 2-density midsole with ZipFoam™ for more long-term resilience and a higher rebound than traditional EVA. The external TPU heel counter and EVA medial post offer rear-foot stability and light pronation resistance. The engineered mesh upper provides a seamless and breathable fit, while the molded foam collar and Ortholite® footbed offer additional comfort. Ultrafly 3 is perfect for the customer needing light pronation support in their women's road running shoes.

More Cushioning and Resilience

In The Press

Mesh Upper is a Win for Sensitive Feet
I love these shoes. I have large, weird-in-specific-ways, hard-to-fit feet. I require a large toe-box...but I also have a narrow heel, and a pesky tailor's bunion that CANNOT TOLERATE anything stiff or firm pressing on the outside of my foot. I tried Topos a few years ago due to the obvious correct ...

Too wide for my wide tootsies :(
I wanted to live these shoes, the seemed like the perfect pair for my wide front foot and narrow heel, and they were great for the first month or so of wear. But, now, I can't even wear them for half a day with out getting terrible pains in my knees and feet. Thinking this pain was from something el...

The perfect combo- the wide toe box of Altra w the 5m heel drop of a Salomon. The perfect shoe. I have tendonitis and plantar facitis and these shoes feel amazing.
Very comfortable with roomy toebox.

Comments about Ultrafly 3
I run roads in the Ultrafly, and trails in the Ultraventure. I love the roomy toe box and the minimal (but not zero) drop. I also really love that they fit well right out of the box; I don't feel like there is much, if any, break-in period. Both models are just the right balance of cushion and stability. I used to wear Altra's, but found the zero drop to aggravate my plantar fasciitis. Topo's, with the minimal drop, are just right. Thank you, Topo! I will never buy anything else! :)

Beautiful vibrant color, lots of toe room and stability!

I can wear these shoes to work, the gym, or just running errands. They are comfortable all day long. I even have room for an insole. They are lightweight and I like that the tongue stays in place, that's a pretty cool feature! I have long toes and these don't ever pinch my toes. I just love them!
Good for wide feet

I use them to run and lift
Comfy right out of the box
I run on a treadmill with these. I'm a new runner, so I feel like I didn't have a lot of insight to contribute other than these are really comfortable shoes. This is my 4th pair of Topos, and I just love them. Their hikers are great and so are these. My feet feel very stable in them, They don't rub anywhere. I am sure I will get more Topo running shoes in the near future. Also, the color is just so fun and invigorating! I feel so pumped up when I put them on.

Great fit! Soles need to last for higher mileage.

Comments about Ultrafly 3
I run half and full marathons. Love the wide toe box, heel fit and I go up 1/2 size from regular shoe size. This is my 3 rd pair. Just wish the soles would last longer than 300 miles. That is why 3 pair in a year.
Excellent toe space

Comments about Ultrafly 3
I was looking for a running shoe that was good for my knees (I tend to over-pronate) and my toes (I tend to scrunch my toes) and was very nervous to switch from an old brand that had been discontinued. However, I read reviews from individuals who had been loyal to this old brand and switched so gave it a try. I have been running for about 40 years and I have to say, these are the best shoes I have found. I am really excited to have found them. They are light, offer great support, and my toes are so very happy. Please don't discontinue them :).

Please offer all colors in a 10.5 Definitely not an extended size. I wear a 9-9.5 in every other running and trail shoe. I need a 10.5 in this one and all of your others. If yours run small (and Topo acknowledges this), you should offer bigger sizes.
