Query: Merrell Jungle Moc

I have been purchasing the Men's Merrell Jungle Moc for about six years now. I have deteriorating Cartilage my knees. This is complicated by the fact that I am teacher who has to be on his feet most of the day. The cushioning of the Jungle Moc actually takes pressure of my knees. It is a great product, and the vendor delivered them in no time at all.
