I keep thinking other Kangoo jumpers will post information about the boots, their experiences, their routines, etc....but still not much out on the web that I can find. This site was one of the first I located when I first heard about the boots and it has some tips and tricks. Doesn't seem to get updated all that often, but it's a place to start if you are trying to decide if these odd looking shoes are right for you.
