Does anybody apply a DWR treatment to their trail runners?

My biggest concert with switching to trail runners for backpacking is the wet-feet issue. I recently got caught in a thunderstorm wearing my new Altras and though I had rain gear, my feet got completely soaked in just a few minutes. The shoes were still pretty wet the next day (indoors overnight at room temperature) so I put them on (with dry socks) and walked about five miles in mild overcast conditions, after which they were nearly dry. Or dry enough, anyway. This leads me to believe that "quick drying" is somewhat of a fallacy, at least under conditions other than sunny and warm.

So, I applied some Nikwax "Fabric and Leather Proofing" to them. I've used this with good results on my Keen Targhees (which also have a w/b membrane). I haven't had them in the rain yet, but the kitchen-sink test looks promising.

I have no problem with waterproof/breathable shoes...I've day hiked in 100 degree temps and backpacked in the 90's with Gore-Tex boots with no discomfort. Maybe my feet don't sweat a lot or something. However, I'm disinclined to lay out another $150 for the NeoShell version of the Altras.

I can honestly say I've never had wet feet wearing boots, other than from accidentally slipping and dunking my whole foot. I gather that if you hike day after day in pouring rain, boots will get soggy, but I've so far avoided that.
