On Cloudmonster - Black - UK 5

Yes, the exceptional cushioning provided by the Helion superfoam and Cloudtec® makes the Cloudmonster Void trainers an excellent choice for long-distance running, including marathons, as they help reduce impact fatigue.

Helion superfoam is a proprietary cushioning material developed by On. It's designed to be lightweight, durable, and deliver both soft landings and powerful take-offs across various temperatures.

The lifespan of running shoes varies based on mileage, running style, and terrain. Generally, it's recommended to consider replacing running shoes every 300-500 miles, or sooner if you notice significant wear to the outsole or a decrease in cushioning performance.

While primarily designed for running, the Cloudmonster Void trainers can be used for light gym activities. However, their high stack of cushioning might not offer the stability required for heavy lifting or dynamic lateral movements in cross-training. For dedicated gym use, a more stable shoe might be preferable.

No, the On Cloudmonster Void trainers feature a breathable mesh upper, which is not waterproof. They are designed for ventilation and comfort in various conditions but will not protect your feet from heavy rain or puddles.

Most runners find On shoes to run true to their standard shoe size. However, fit can be personal. We recommend referring to On's official sizing guide or trying them on to ensure the best fit. Info needed: (Always check the specific size chart if available).

Ensure you are wearing appropriate running socks to prevent friction. Re-lace your trainers, adjusting the tension to relieve pressure points, and ensure they are not tied too tightly.

Regularly check the outsole for embedded debris like small stones or mud, and clean it thoroughly. While the rubber outsole provides good traction, exercise extra caution on very wet or slick surfaces.

Remove the insoles after each use and allow both the insoles and shoes to air dry completely. You can also use athletic shoe deodorizers or sprinkle a small amount of baking soda inside the shoes overnight.
