Nice! Sadly these are 10N, I’m a size 10 1/2 so these are a bit tight, not too tight but hopefully over wearing them time by time they’ll loosen up.
They do, I wear mine when Iride my bike, though you get the mark of the shifter
You wouldnt burn you leg on the exhaust pipe? cause the side wall of the boot is canvas 
Forive my ignorance Ive never driven a motorcycle before
