I have read threads on what people like for camp shoe wear and for me flip flops are fine but, what would be a good light sandal/shoe when you want it to double for stream crossings. I hiked Eagle Rock Loop last spring and wore crocks but they were very unstable and slippery when crossing the Little Mo river and creeks many times. Can anyone suggest a sandal/shoe lighter than a teva or chaco? or does the versitility of these make it worth the taking?
