I wear a road ID dog tag. Honestly, if I were doing it again, I'd just buy cheap-ass dogtags online. You can get them for about 5 bucks. Sure, the Road IDs look real pretty, with their acid-etched letters on shiny tags, but for functionality I bet a regular old stamped dog tag works even better.
I can't stand wearing bracelets, and the shoe thing didn't seem smart to me since even in car accidents I've seen shoes come off, and on a bike where your shoe is actually attached to the pedal, it seemed like the shoe could easily go flying off into the brush.
In my case it's just ID; the medical info is that there is no medical info; no meds, no allergies, no issues of any kind. But it does have my blood type, though I doubt they'd trust it anyway; in emergencies I'd guess they use O-, in non-emergencies they'd have a chance to type me anyway.
