Black Diamond Momentum Lace sizing

Size down about half a size from your street shoe

For a snug all-round fit, a street UK 9 (EU 43) is a UK 8½ (EU 42½) in the Momentum Lace. 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.
