La Sportiva Tarantula Boulder sizing

Size down about 1½ sizes from your street shoe

For a snug all-round fit, a street UK 9 (EU 43) is a UK 7½ (EU 41) in the Tarantula Boulder. 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.
