Customer Reviews

  1. Great Hiking Insoles Review by Tom

    I really appreciated the time your customer service rep (Tyler) took with me on the phone today. I have been looking for both the Old Spenco Dayhiker & Spenco Backpacker Insoles and while you carry them under "discontinueds", you didn't have my size. Tyler took the time to explain that the Spenco Earthbound is the replacement insole and the details of how it is built and it's specialties.

    The Insoles are great and just like the old Dayhiker's & Backpacker's -Thank you!

  2. Excellent for hiking Review by Tim

    After looking around and trying just about every hiking/backpacking insoles on the market, I came across the earthbounds. I was experiencing intense pain in my metatarsel with every step, The uneven ground seemed to cause me the most problems and that is all I get when hiking or backpacking. I got these insoles and wore them around to kind of break them in. Then I went off on a 2 week hiking trip. I cross my fingers and held my breath that these insoles would do what no other insoles have done before, that is, alleviate the pain. Hoorah! Finally, I found something that works. No more pain, no more worry about hiking or backpacking. I now can walk all day without any problems. You can bet I am telling all my friends about these, I would highly recommend them without any hesitation. Great job spenco! (Posted on 4/12/2010)

  3. The Earthbound insoles support my ankles and make my feet feet better. Review by Bennie

    They're supportive, and my feet felt better at the end of a long day than in the insoles that came with my boots. I've worn the new Earthbound Insoles for about a month mostly hiking and walking, and I forget they're there--a good thing in an insole. That's because my feet do not hurt, and my bad ankle is less wobbly--the insoles are doing their job. (Posted on 2/12/2010)
