Choosing the right running shoe can make or break your performance—and your knees. On Running’s Cloud series has exploded in popularity across South Africa, thanks to its perfect mix of technology, comfort, and modern design. But with so many models—Cloud X 4, Cloudsurfer, Cloudflow 4, Cloudrunner, and Cloudmonster—how do you pick the best one for your goals?
This 2025 guide breaks down the major On Cloud models so you can match your stride, training needs, and comfort preferences with precision.
☁️ What Makes On Cloud Shoes Different?
All On shoes feature CloudTec® cushioning, a unique hollow pod design that compresses on impact and rebounds with energy. Most models include the Speedboard®, a plate inside the midsole that propels your foot forward and adds structure. Combined with premium materials and often recycled uppers, On shoes deliver performance with minimal weight.
