I too am intrigued by these quick-drying shoes. Up to now, I've just used the "conventional method" of changing into and out of "water shoes" upon stream crossings. Not a huge burden, but a series of annoyance nevertheless.
I enjoyed the article as well, and would like to see it expanded (perhaps in another article) to a discussion of socks also. When it comes to crossing a stream and then squishing out the water as one continues to hike, I can only assume that the socks one wears will have a direct impact on water retainage, drying speed, and in the end, feet comfort?
