So my wife just got back from having her toenails done, and they give her these little "sandals" to wear while you walk around the store. I have been using crocs (8.7oz!!) for a long time, and once I found this forum I switched to homoemade blue foamy sandals (1.4oz) (not nearly as comfortable as crocs, and useless fording streams)
Anyway, I am secure enough in my masculinitly I tried on her nail/spa sandals and whoa! they are more comfortable than my blue foamy sandals and they weigh .4 oz!! That's the same as my car key man.. Also they are perfectly flat so they won't take up much space.
I'll probably get 2 or 3 and ship them to myself when I do resupplys and see. I will miss the crocs though, as I use them when I shower at night before bed in usually freezing streams, but no way is that worth a half pound.
