Unparallel Sirius (last season) sizing

Size up about 1½ sizes from your street shoe

For a snug all-round fit, a street UK 9 (EU 43) is a UK 10½ (EU 45) in the Sirius (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.

Sizes the same as the Unparallel Sirius.
