as catch23 said, one big thing is feeling rocks under your feet. Another thing is that for the first bunch of runs, you will feel pain.. this is mostly because your feet aren't used to working out and they will hate you for it. But it does build of foot strength. And I mean it won't turn a fat person skinny.. and it won't make running the most wonderful thing in the world (unless you already enjoy it), but it will make things better, hence the "not a saviour"

I hear you on the "skymall-ish" comment... but trust me it's definitely not some crap like that, it's solid, and I highly suggest everyone at least try them out.
