    You always have reservations when trying a company for the first time. I LOVE how high quality and well designed these shoes are... I will go so far to say I anticipate they will give my disc golf game even a better score for the great support on my feet AND them being water proof as well. Thanks to all the people at Keen for making such a high quality product!

    Did not meet expectations

    So it's a waterproof shoe. Unless you are going to ONLY wear these when you want to protect against getting wet, your foot will not breathe, at all during every day use. This means that you will have hot sweaty feet, all the time. Nobody wants that. In addition, I've had these shoes about 9 months, only wearing them maybe once a week and the tread on the bottom is already worn out. For $150 your shoes should last MUCH longer than that. I have North Face hiking shoes with Vibram soles that are over 10 years old and have more tread than these.

    Made in China.

    I'm not sure why these come up when you limit your search to "American Built". The ones I received were made in China. Back they go. If you would just give us more country of origin information, customers could make more informed purchases and not waste time, money, and fuel shipping products back and forth. I appreciate Keen's commitment to U.S. manufacturing and I would like to support those products made here.

    Keen Quality PNW Worthy

    5

    Living in the PNW waterproof is a high priority. The Aphlex takes it to a new level with great support, mud clearing lugs and lightweight. I've been in these for about a month now and so far am impressed. Hiking on the Olympic peninsula coast of Washington allowed for a great test in mud and wet conditions. They handled steep slick trails without a problem and my feet were protected from becoming soaked during full days of rain. Thanks Keen!!!
