ON Cloudflow 4 Running Shoes in a men's size 11 (EU 45). These are in the Glacier/Chambray color, and are an excellent lightweight shoe for fast training runs, and race day. They have a low, but responsive, cushioning, an 8mm heel-to-toe drop, and a forward roll design. These have seen just under 100-miles, and show some dirt on the soles and upper. Aside from that, they have a lot of quality miles left in them.
