Each CloudTec® cushioning pod compresses on impact and springs back, giving you a softer landing and a more energetic toe-off than traditional foam alone.

The integrated Speedboard® plate guides your foot through each stride, adding propulsion so the shoe works with your natural gait rather than slowing it down.

Hidden eyelets and a refined Glacier | Alloy palette give the Cloudmonster 1 a polished look, while Helion foam and a rubber outsole keep it ready for real-world wear from the first step.
Product story
The Cloudmonster 1 in Glacier | Alloy was designed for the kind of runner who logs miles in the morning and then keeps going. The cool glacier tones and brushed alloy finish give the shoe a composed, versatile look that holds its own on the road and off it. Hidden eyelets keep the profile clean, so nothing disrupts the streamlined silhouette.
Under the foot, the CloudTec® cushioning system does what On engineering is known for: each hollow pod compresses independently on landing, then rebounds to push you forward. The Speedboard® works with that motion, adding propulsion so the shoe doesn't just absorb energy, it returns it. Helion foam in the midsole stays light underfoot while holding its shape through long days and high mileage.
This is a shoe for everyday wear, not just race day. Wear it for a 10K before work, a grocery run at noon, or a long walk through the city on the weekend. The rubber outsole delivers reliable grip across surfaces, and the ride is forgiving enough for runners who are on their feet for hours at a stretch.
The Cloudmonster 1 suits runners who want maximum-cushion comfort without a shoe that looks like a statement piece. The Glacier | Alloy colorway in particular appeals to people who prefer a cool, understated palette. Whether you are building a base, recovering between hard efforts, or simply looking for a go-everywhere shoe that can keep up, this is a strong answer.
