Very fast shoe that is an improvement on the previous Streakfly with addition of the carbon fiber plate. The responsiveness is great and I can tell that when I race in these I'll be primed for a PR. Be sure to lace tight as the tongue does have tendency to slide to the side slightly. I would have preferred if the material in the heal was sturdier, but I understand this shoe is all about weight. Great shoe, put them on and fly!

I LOVED the first streakflys. Have them in 3 colors. I was excited for these to come out and they are disappointing. So different from the first version. And the colors are not as fun as the first ones. I really hope these shoes are redone again and closer to the way they were the first time.

AVOID. One 3 mile pavement run and the heal is falling apart on both trainers. Sent back for a refund. Awful quality.
