jeffstreetwrote a review of Shimano RX8 Mountain Bike Shoe - Men's on January 22, 2020
Familiarity: I've used it once or twice and have initial impressions
EU 47 = US 13 (Nike).
Shimano's size chart calls for 48, which is definitely too large. I could probably squeeze into a 46.
EU 47 = 325 g, each.
Fits Crank Brothers Eggbeaters without traction pads.
