I've had Keen sandals for a few years and the one thing I liked was the sole. I ordered a different pair a couple weeks ago and they looked and felt as expected.  I received these yesterday and the sole felt plastic and they were lighter than expected. The sole didn't have that anti-slip feel to it. Fortunately, I bought these to wear around the house, but I was still disappointed. Didn't feel authentically Keen. Just okay.
