Im also typically walking on uneven ground and up and down steep hills. (This is going to be hard to read but I am making a point by using my defective keyboard to write this review) << I spell checked this line only. I have used them on Quitcomort and it did not change any quality from its original counterpart in terms of looks and comfort. It is easy to install, has the hardware needed, and looks nice installed. High-quality material, and it even got more sound isolation than the original pads. A week after purchasing audio cuts in and out. It?s easy to install and works well keep my towel warm They look worn in and adjusted to my feet and movement habits. aIt is a well made shoe. What was once crisp nice audio is now worst than a mic on a phone.
