Setup: Your On Running Cloudmonster shoes feature a standard lacing system designed to provide a secure and bespoke fit. Upon first wear, adjust the laces to achieve a snug but comfortable feel across your midfoot, ensuring your heel is secure and your toes have enough room to splay. Ensure even pressure to avoid hot spots during your run. Compatibility: These trainers are specifically engineered for road running. Their durable outsole and cushioning system are optimized for asphalt, concrete, and other paved surfaces, providing reliable traction and impact absorption. While versatile for daily training, they are not primarily designed for trail running or highly technical off-road terrain. Care: To maintain the performance and longevity of your Cloudmonster shoes, it's recommended to clean them gently. 1. Remove any loose dirt or mud by tapping the shoes together or using a soft brush. 2. For surface stains, use a mild soap mixed with cool water and a soft cloth or sponge. Gently wipe the affected areas. 3. Avoid submerging the shoes in water or using harsh detergents, as this can damage the materials and cushioning. 4. Allow the shoes to air dry naturally at room temperature, away from direct sunlight or heat sources, which can degrade materials. Do not tumble dry. 5. To maintain freshness, you can remove insoles and air them out separately.
