Very impressed with the bubble envelope slippers. Did you stick an insole from another shoe in there?

I have classic Chacos and I left them in my car on my last trip, thinking they were heavy, it was just one night, and I was fine not having camp shoes. Seven non-trivial creek crossings the last half mile before camp. I was wishing for the extra two pounds. I have some VFF KSOs, too, that I could/should have brought.

I'd really like a light, comfy closed toe camp/water shoe for occasions like that. Something I could barefoot or sock, less than a pound for the pair, won't get punctured on a stick or rock. Am I being greedy?
