Puma running shoes with a lightweight and breathable design. - Brand: Puma - Color: Black - Model Name: Deviate Nitro 2 I've run about 100km in these, and they're still usable. Recommended for those aiming for a sub-4 marathon, or as a first carbon fiber shoe. I'm selling them because I achieved a sub-4 and bought different shoes to aim for 3.5. Type... Running Shoes
