I actually saw these suggested on a Bikepacking forum. They are $9.99 on Amazon so I ordered a pair. 10.5 oz for size 13. They feel like nothing on your feet. They are very light, but not necessarily so compact like a pair of 5 Finger shoes. They do seem like they would reshape well if you smashed them in the bottom of your pack. They are made from a foam material (even though they look rubber) that doesn't hold water so they would make fine river crossing shoes. I've never carried camp shoes in the past, but I'd consider it on short trips if I knew I had river crossings. I got them primarily for paddle boarding actually, but I know a lot of folks like to carry a camp shoe.
