I'm looking for a new pair of walking shoes that could also be used with a pair of slacks as casual business wear (i.e. doesn't have to go with a suit). I'm looking for a pair that won't set off the WTMD and doesn't have a thick sole. So far the Ecco website isn't turning up a lot of information. Any other brands I should consider looking at?

I tend to bring just one pair of shoes so it has to be good for extended walking in a city/light trail hiking but should also be wearable for business casual and into a nice restaurant.
