I went with the Timberland Radler.
Probably not the lightest option, but they are lighter than my Chacos!
I bought the Virobarefoot Ultra Pures too. They weigh 8.3 oz for pair of size 10's. I did not buy them for camp primarily. I bought them for fording. Will where them at camp too though. If you buy them, get them 1 size down. I take an 11, and the 10's I got are barely too big. I am not sure if the makers think you will be wearing socks or insoles or something. They run big. Love them.

Teva, Merrell and several other brands now make a very light weight trail/running/river shoe. They look like trail runners but are made with reinforced mesh, weigh near Croc weight, can be worn with socks or without, can be worn in camp or in town AND can replace your regular hiking footwear in case they become damaged.
