I love my old sheep-Zakinthos lined merrell clogs. I have them for at least 10 years. Every now and then I replace the insoles with new sheep-skin. They are beginning to look a little ratty so I thought I should replace them. The closest I could find were the fleece (ie artificial) lined clogs. Not nearly as comfortable or warm. In fact, a big disappointment. I may send them back. Why,oh why, do the mess around with a perfect design.
