its a motorcycle.. you are vulnerable..
there are many quality riding boots/shoes
aside from all out racing boots..
recommend rs taichi delta boa riding boots
which are a compromise in design but
imo perfect general riding boots/shoes..
RS Taichi RSS007 Delta BOA Riding Shoes
also have excellent alpine stars full boots
for longer rides esp in cold and rain etc..
the shoe part is the main part tho,
genuine riding shoe/boots have crushproofing
and suchlike safety elements with long boots
taking protection that much higher to calf level..
but for a first quality riding shoe/boot
you cant go past those taichi with stainless steel
wire cable fasteners, for security in an off
plus easy fine adjustment, removal etc..
theres no such thing as '250 riding boots'..
you could hop of a 250 onto a 500 etc
without changing your boots [!]
