Extremely Comfortable Shoe

Comments about Ultrafly 4

I bought these for general all around wear. They are one of the most comfortable pairs of shoes I've ever worn. They are very light, the fit is true, and they offer good general support.

Bottom Line Yes, I would recommend to a friend

Great Running Shoes!

These are outstanding running shoes. I have a mild overpronation which these handle perfectly. Not to soft or firm. A big thanks to my local running store, Corey at Mountain Running Company for helping me find these! Love these shoes!!

Nice shoe. Just not for my feet.

I have very flat and straight feet. These were simply not straight or wide enough to fit comfortably. Perhaps a wide would work.

Why an incomplete sole?

Submitted

By Andrew

From Knoxville

Really like ths3s shoes. Fit and finish of them is great Like the toe box and less rise than other shoes. But Topo what are you doing?this is their only stability shoe and the forefoot of the sole is uncovered foam. Why? This area wears out much yicker than the shoe itself. If they continued the abrasion resistant tough part of the sole through the whole under side it'd be great. With the exposed foam...not worth it. I tried two pairs because I like the shoe and the minimal rise but won't buy another. I'm a 36 year old runner...I need some support. Have the ultraventures for hiking and trails. Great shoe but too stiff to wear on the road for me.

I need this shoe in a womens fit but you don't make W13/ 13.5. Toe box is fine but really not narrow enough in arch area . I keep lacing it up tighter and it the loosens up. So I do think it is a good shoe but the sizing for me is not great. Actually depending on how far I go my feet hurt a little afterwards.

Bottom Line Yes, I would recommend to a friend

Hret fit and nice running but major flaw!

Submitted

From Knoxville

This is a nice shoe. I've had 2 pairs for road running. Comfortable shoe and runs. The outsole is horrible though. There is no rubber over the forefoot of the outsole. I have no idea what topo is thinking. Save money? Save weight? Current shoe is about 200 miles and the foam is worn through. Unfortunately there are no other stability road shoes. If they covered the full out sole with good rubber this would be 5 stars. There is no puncture resistance. One its worn there is no grip (I'm in East Tennessee. Going down hill on wet asphalt with no rubber on the forefoot and the foam worn out is ...not safe and slick)

Bottom Line No, I would not recommend to a friend

I like the fit of the shoe. But sole durability is terrible

Submitted

By Ben

I use them for walking only on side walks. Maybe 10 miles a week. All of the exposed foam on the bottom wears out. The rubber sole is fine but it is not enough. Where the ball of your foot hits its foam. Like it is planned to wear out. I have not even had these 4 months.
