On’s Burna Boy edition comes in two shoes, and both carry the BB suffix in the name. On has given no price, run size or release date for either. The Cloudmonster BB is monochrome red, with an engineered-mesh upper and the laces and the logo and the open-pod CloudTec midsole all dyed to match. Wearing a musician’s initials on a running shoe is a small public statement, and most people who make it would prefer not to be asked about it. THE ROGER Clubhouse BB is all-white leather with perforated quarter panels and a flat cup sole.
