My girlfriend just broke 3 toes at parking garage speeds, while ATTGAT -- her boot sole (Diadora something-or-other street boots) rolled under and she hyperextended her toes. Aside from a nice bruise on her thigh, no other damage though.
So now we're ATGATT+motox boots w/ hinged ankles... Much better protection, and I kind of like my feet the way they are -- ski season, and that whole walking thing, you know?
And last year I had a partridge run out of the weeds at the side of the road at the last second and attack my shin at 65-70mph. That really smarted. Well, it hurt the partridge more. When I looked back all I saw was a cloud of swirling feathers. With the motox boots I'm not sure I'd even feel it now...
