The Cloudmonster 2 is On's big-cushion road trainer. A nylon-blend Speedboard sits under the largest CloudTec elements On makes, and the 6 mm drop keeps the roll forward rather than the landing sharp. It is the shoe for easy days, recovery days, and the long run you want to survive rather than attack.
It suits you if you like a tall, bouncy ride and do not mind carrying it. At 300 g it is a heavy shoe, and the weight is the price of the stack.
It is not a tempo shoe and it is not a racer. If your week has a workout in it, buy something lighter for that day and let the Cloudmonster take the easy miles.
