I once ask a question about riding boots and got this reply. Motorcycle riding boots that are made well should have a wide and thick sole with tall leather tops. Thick sole - to help protect from the very hot blacktop surface. Wide sole - to help stabilize you when stopped with a heavy bike. Tall leather tops - to protect you from the pipes and the motor heat.
I bought a pair of Harley Davidson boots and took the copper/brass emblem off from the side of the sole and replaced the emblem with another that a friend made for me that said Yamaha. They say HD on them high on the boot but it is covered by my pants.
