Is the Cloudboom Volt good for actual running?

It is built on On's marathon racing design, with CloudTec, Helion HF foam and a carbon Speedboard, so it can handle training and fast runs. On positions this PAF version as a lifestyle sneaker, so most buyers wear it casually.

How does it compare with the standard Cloudboom?

It shares the racing platform: CloudTec cushioning, Helion HF foam and a carbon Speedboard in a segmented midsole. The PAF version adds structural, avant-garde styling and is aimed at everyday wear rather than pure race day.

Does the carbon Speedboard make it stiff?

Yes. A carbon plate stiffens the midsole for a propulsive, rolling feel when running. For standing or walking all day, some people find that firmness less comfortable than a plainer lifestyle sneaker.

What is the upper made of?

A mesh and synthetic upper. The mesh adds breathability, while the synthetic overlays create the structural, layered look of the PAF design.

How does the Cloudboom Volt fit?

Sizing is listed in U.S. men's sizing. The shoe has a performance-style fit, so try your usual On running size first and size up if you prefer extra room in the toe box.
