No idea, but if I'm right in assuming they're super-shock-absorbing(?) and you train in nothing else, your stabilisers/various muscles and whatnot in your lower legs might not develop as much as they would otherwise.
Personally, I don't like relying on impact absorption in footwear (it's probably necessary for long-distance runs, but I don't do those); I'd rather build up flexibility, endurance and strength in my lower legs. I mean, if the only thing preventing an injury is my shoes - I need to be doing something different or conditioning more first. So I train in Chinese Feiyue shoes (light, flexible and cheap) or bare feet.
If you're running, get some good running shoes that fit you well. If you're just walking around for short durations in everyday life, I doubt it matters much what's on your feet.
