Hi. These are very lightly used. Size 43.5 and the old regular width, now known as their narrow width. Please reference their size chart. These are really light, dual BOA and use their dual carbon sole. Carbitex carbon fiber inner paneling for a secure fit that transfers power nicely. Very cool technology. For reference, in a Specialized I wear a 43 and Shimano I wear a 44. Never crashed. Non-smoking home. Comes with replacement box. New retails for $380
