When I first got my scooter I bought a pair of Docs just like that for my riding boot. They were way to lose around the ankel and provided just as much support as a tennis shoe. They only thing they had going for them was they would at least stop road rash if I crashed. But my ankles would both be trashed if not snapped off.
I sent them back and found a proper riding boot that zips up past my ankel and provides tons of support. The boots I found were Bates Enforcer Tactical Boots shown here. They are super light and provide plenty of support for riding. If your going fashion over function then get the Docs if not ditch the idea.
