That's the boot I wore for months last year.
Hadn't I been wearing my riding boots at the time of the "incident", would have been much much worse. Bad, and painful enough as it was.
You don't have to go fast to need boots, after I dropped my heavy bike at 0 Mph some bystander came to my help.....when he got there he promptly stepped on my leg/ankle in his excitement and ripped my Achille's tendon. According the specialist that left me with the rather large scar from surgery, would have been way worse without proper boots on.
