I bought these shoe trees for a pair of Clarks Desert Boots that I was having a hard time breaking in. The boots were causing a lot of pain on top of my foot just around the toes. Several online reviews and forums suggested shoe trees as a way to remedy this issue, so I figured it was worth a try. I was not disappointed. The Clarks boots broke in much easier after using the trees, plus they have a great cedar smell that can't be beat. And of course, my boots are keeping their shape and my feet are feeling good.
