They pack flat and will take much less space than the crocs I was using (hence they'll be in my pack rather than hanging outside).
I've got wide flat feet (surprise surprise) so they're a little uncomfortable but will be okay for short walks. I wouldn't want to walk all day in them. They've got good toe protection too

I think they are light enough to for rocky creek crossings on day walks too.
The crocs I had been using are a sandal style (that was discussed/pictured on these forums) and seems to have been discontinued. I can't find the thread where someone posted a photo of the particular crocs.
