This is our first time buying a "waterproof" winter boot from Keen. We bought a pair of these for our son before Christmas. We took them on a 4 day trip to the snow... they failed us big time. His feet were soaking wet most of the 4 days and we could NOT get them dry. We got home and immediately purchased a better WATERPROOF pair... and they have been perfect. Won't buy winter products from Keen again.
