They are not completely different boots.........
They are the same shell
both have 98mm lasts
both have 3 piece carbio design
both have medium flex kinetic response tongues
both have firm foot boards
both have power cuffs
both have the dyna link buckle
both have twin canting
both have forward flex control
both have frward lean control
both have F-100 aluminum buckles
both have D-62 PU shell/cuff
pros come with a spare stiff flex tongue and a spare anti shock footboard
crosses typically come with a silver i.d liner (medium density foam) while the pros come with a gold i.d liner (high density foam)
but his thread title says gold liner so there is no difference between his boots and pros besides spare parts.
