Most of the shoes recommended in this thread are breathable but not waterproof. I've always assumed that one would want shoes that will not get soaked through in a rainstorm--i.e., with Gore Tex liners. Can you experienced walkers comment on this?
A shoe getting wet - and by extension, feet getting wet - is not a problem.
The problem is shoes (and feet)
staying wet.
Waterproof boots, particularly goretex, take a long time to dry when they get wet inside. And they
will get wet inside. One, a heavy, persistent rain will find its way in at some point. Two, feet sweat. And "breathability" only goes so far. A humid environment inside a boot, particularly a "waterproof" one, is asking for blisters.
I generally don't believe boots, WP or not, are necessary or advisable for 3-season hiking or backpacking, Camino or wilderness.
Now waterproof
shoes are a different matter, in my experience. Because they are so low profile, breathability and fast-drying are enhanced.
I was skeptical the first time I tried my now-beloved Ahnu Montara WP's. But I actually appreciate that they repel wet grass/dew, light rain, and low puddles. Of course they still get wet inside in deeper water and heavy rain.
But they drain and dry quickly. That's what matters.
With low profile shoes - hiking shoes or trail runners - waterproof can be a nice feature, but is not required by any means.
When I encounter stream crossings, for example, I rarely bother changing into water shoes - whether I'm wearing my Ahnu WP's or my Brookes trail runners. I just splash right through. My shoes are wet for a bit, and I walk them dry. I never get blisters.
