The new Cloudflow 4 shoe is now one of the lightest On Cloudflow shoes ever designed, weighing 200 grams in the women's size range and 235 grams for the men's sizes, with a 9mm heel-to-toe offset.

So what makes this 4th edition of the Cloudflow running shoe so different from its predecessors?

• The brand-new upper, made from 100% recycled polyester, draws inspiration from the layout of the fast, carbon-infused Cloudboom Echo 3 performance shoe. This results in a speedy and lightweight road running sneaker that offers enhanced airiness during scorching summer workouts and running training sessions.

• Ideal for fast training sessions as well as 5km to half marathon races ‚Äì especially for lighter foot runners.

• The new Cloudflow 4 features a fast Speedboard¬Æ with improved stiffness and strength, alongside CloudTec¬Æ in Helion‚Ñ¢ dual-density superfoam throughout the shoe. This new design from On absorbs more shock, providing further protection to your knees and feet, effectively offering more impact absorption.

The final outcome is a shoe that is even more receptive - providing next-level energy return, more strength, efficiency, and gentler impacts for your legs. If it is "fast" you are looking for in an On running shoe, then the new Cloudflow 4 is definitely one to consider.

Fast is now for everyone:

• You wanted speed. So we added a spoon-shaped nylon blend Speedboard¬Æ that's stiff, strong, and lighter than before, combined with a powerful forward roll to catapult you to new personal bests. Put simply, you'll feel it.

• Looks light. Feels light. The ultra-light woven upper takes a cue from our fastest shoe yet ‚Äì the Cloudboom Echo. The result? Breathability and performance that makes picking up the pace easier than ever.

• Softness like never before: CloudTec¬Æ in Helion‚Ñ¢ dual-density superfoam now runs throughout the shoe, offering impact absorption that makes every stride softer underfoot. This also gives back an ultra-responsive running sensation, crucial for going faster and staying faster than ever before.
