They're actually not Crocs, but something that starts with a "K"...don't know their name, as we've lost the box and the shoes don't have logos on them. (what were they thinking?)

They are made of the same material as Crocs, but lace up with bungie cord so they seem to stay on my feet better.

I was not a fan of these at first. Like jim, I always just assumed that I wore one pair of shoes backpacking (a pair of relatively light boots) and that anything more than that was overkill and a waste of weight.

Then my wife started carrying a pair of Crocs...she likes to use them for stream crossings--keeping her boots dry and saving wear and tear on her feet. But she fell in love with them in camp. She takes her boots off and sighs in relief every evening--letting her feet breathe after a long day on the trail. I got tired of her satisfied sighs of delight, and decided to try my own pair. I am sold on them, for all of the above, plus wading when I am fishing.

And they literall weigh 11 ounces--carried strapped to the back of my pack fo easy access. I think I paid all of about $15 for them.
