All sizes are EU whole sizes — no half sizes. *US conversions are approximate: a whole EU size often falls between two US sizes. If your US size or foot length lands between two rows, choose the larger EU size.

How to measure your foot

Place a sheet of paper on the floor against a wall. Stand on it barefoot, heel touching the wall.
Mark the tip of your longest toe on the paper with a pencil.
Measure the distance from the edge of the paper (wall side) to your mark.
Compare your measurement with the Foot length column above and read your size across.

Tip: measure at the end of the day — feet swell slightly — and use your larger foot.

The Cloudboom Volt is built for speed, pairing a carbon Speedboard with supercharged Helion HF foam for maximum energy return on every stride. Its ultra-light, breathable upper keeps weight to a minimum, while an optimized drop is tuned to help you fly from the 10K to the half marathon. This is a race-day weapon for runners chasing personal bests and podiums alike. Responsive, propulsive, and featherlight, the Cloudboom Volt turns your training into momentum when the gun goes off. Carbon-plated propulsion, hyper-charged cushioning, and true racing feel — lace up and let it rip.

A running shoe first: cushioned for daily mileage, and stable enough that long runs don't turn into a negotiation. On's CloudTec sole is unmistakable underfoot — a soft first contact that firms up as you roll through the step.
