Ocun Ozone (last season) sizing

Size up about half a size from your street shoe

For a snug all-round fit, a street UK 9 (EU 43) is a UK 9½ (EU 44) in the Ozone (last season). Go half a size smaller for hard bouldering, or bigger for long days. It's a starting point: feet differ, so try them on if you can.
