Worn once- great road running shoe just a little small for me. Fast with carbon plating! Make me an offer The Zoom Fly SP is a fast shoe. A fast shoe that looks fast – even while standing still. Every line celebrates speed, from the streaking Swoosh to the race-track-like lines it parallels. A digital clock graphic pays homage to the historic Breaking2 attempt – Nike's moon shot to break the two-hour marathon barrier – as do the tongue icons seen through the translucent upper.
