I was looking for a waterproof hiking shoe and bought the Conspiracy Titanium OutDry Trail Shoe from Columbia a few months ago after reading this review https://gearjunkie.c...ail-shoe-review and I love them.
They are extremely comfortable, waterproof yet breathable and have great traction.
I had the opportunity to do some hiking at the Delaware Water Gap last week and the shoes kept me dry while walking through streams and provided good grip on wet rocks and steep muddy trails.
Outside of hiking I've worn them in snowy urban conditions and found they performed great for that as well keeping my feet dry and and my footing solid.
The reviewer mentions wearing them on a 24 plane trip without experiencing clammy feet. I have not flown with them on for that long, but I did recently wear them on a 2 hour flight and it felt no different than wearing regular sneakers. However the waterproof technology works it works well while letting your feet breath.
I found the fit true to size and bought them from Getz's
