Fantastic shoe and amazing upgrade!

I don't write reviews, but these shoes deserve it! This is my 5th pair of Ultrafly's, dating all the way back to the original model and these may be my favorite. I need the little bit of stability they offer and enjoy the lower 5mm drop. Just took them out on 8 miles right out of the box and they felt great! The biggest difference noted as soon as I put them on was the increased amount of cushion. Maybe it was just the "new shoe" feel but I did feel it all the way through the run. Some of the small tweaks make a huge difference. I love the new mesh upper, it felt like it hugged my foot without being too tight and was very breathable. I felt that the heel fit was much more snug, no slipping at all and I didn't have to lace the shoes to lock the heel (had to do that on the first two models) and the double eyelet on the tongue helps. As always I love the large toe box. There is no size fit difference between the ultrafly 2 and 3, same size true to fit. I am interested to see how the decreased amount of rubber on the sole affects the total mileage over the life of the shoe but I appreciate the decrease in weight it allows. Overall, a fantastic upgrade! Thank you Topo!

A great roomy came comfy trainer. Topo fixed everything I didn't love about the Ultrafly 2. Lighter, more comfortable upper, perfect tongue. Better groundfeel and smoother through contact to toe off so not plodding at all. My favorite Topo since the first Fli-lyte.
