  • 19.2 miles in the High Uintas with my Aphlex boots

    5

    I just did 19.2 miles in these boots to Ryder Lake in the High Uintas Wilderness here in Utah. These boots were put through rocks in the trail, water crossings, muddy and boggy swampy sections, and the steep climbing with a UL backpack on was great because these boots give you traction. They passed every test that trail gave them. My feet never hurt and they were dry throughout the whole trip. I have had mine for two seasons and I have to say these are some of the best backpacking footwear I have ever owned.

    Great for almost everything!

    I am very happy with my purchase of this boot. The fit was excellent and the arch support is superb. When I bought them I needed a light hiker that I could wear to do landscaping, to my son's baseball practice and in the winter. These have served all my needs but I did wear them while removing 2 feet of snow during a noreaster last year and I realized that if you own these you they're not a snow boot. I will say that I wear these all year and have had to wear my big bulky snow boots less frequently.

    Do NOT waste your money with Keen!

    Do NOT buy these boots if you need even water resistant boots. Hubby got these for work, and even just walking through wet grass leaves his feet wet all day! He tested these by standing in a container or water for a couple minutes and they worked great, until a month later. Keen replaced them with their warranty program, he got two pairs of different styles (Men's APhlex Waterproof Boot and Men's Oakridge Waterproof Boot) with the sale, that were also "waterproof." And you guessed it, a month later, soaking wet feet just from wet dew. Now we're being told that we "agreed to the warranty terms by accepting the warranty voucher, so nothing else can be done." The warranty voucher was our only choice, and now he's left with 3 pairs of water absorbing Keen's. Find another brand! And if you know of a good one that can withstand actual water for more than a month, email me! Again, Keen's are a WASTE of money!!!!

    Best day hiker in a while!

    5

    I recently got the Aphlex boots and they are comfortable right out of the box, like a favorite running shoe. From the traction of the sole pattern, the light weight build, the laces that lock your foot in, this boot is a new favorite for all short hikes.

    Happy Feet!

    I LOVE these boots! They are light weight, waterproof, and extremely comfortable right out of the box! No blisters, no break in period! I live on the West Coast a.k.a. the Wet Coast and I hike, camp,and mountain bike in these boots, as well as wear them daily during the rainy season. These are definitely the most comfortable and versatile boots I've ever owned. I totally LOVE these boots -a very worthwhile investment!

    Waterproof & Light Weight

    5

    I have now had these boots for 6 weeks and hiked 3-7 miles a day without any problems. Very good support, light weight, and waterproof. Living near Grand Teton National Park I've used them on a variety of trails from hard packed dirt to rocks and crossed many streams by just walking through the water (less than ankle deep). The tread is not as deep or aggressive as other "hiking boots" so if you need large deep lugs, I'd look to other boots. Also, mud is easily washed off these boots.

    Best shoes eveeeer! Was nervous after taking them directly from the store to the trail-head of a 20 mile backpacking loop, but they were amazing! Extremely comfortable with no-break in period required, while also being very supportive and breathable. Great combination of fit, function, and style - KEEN has nailed it with this boot.
