Purchased in July, I've run about 15km on roads and tracks. Selling because they don't suit my needs. I'll answer any questions or requests. I plan to ship them in the box shown in the photos. Price negotiable. Puma Propio Nitro Weight: Approximately 140g, Drop: 4mm 20mm thickness provides a good ground feel. Recommended for speed training, short-distance drills, those who want to feel the ground and get a good rebound, and those looking to build strength.
