 tier cushioning system that you won't find in any other slipper. It combines two layers of foam, including my proprietary MyPillow foam and a patented impact shell made from U.S. soybeans. My three tier cushioning system is going to help relieve pressure points, provide that micro support you need for all day comfort, and help prevent fatigue. Not only that, my slippers are made with high quality leather and a premium indoor-outdoor sole that makes them extremely durable. I personally guarantee they're going to be the most comfortable slippers you'll ever own.
