The last time I saw this discussed was in the 1990s when John Kocinski used to wear the legs of his leathers outside his boots in World Superbikes. Whatever is most comfortable I'd suggest.
I saw a right throbber out today - riding with his jeans OVER his boots!
Just messing - do what is comfortable for you - bks to what anyone thinks! I ride with my gear (be it textiles or jeans) over boots as that is what I've found works best for comfort and keeping the water out!
Definitely tucked in. Looked so cool with my black/red boots. Photo outside the cop shop where my mate with the GSXR was "producing his documents". c1988
