Pack of four custom-molded silicone feet help to keep the Encore in place on your desk. Encore feet have no adhesives and are friction fit into milled slots in the Bottom Case. 

These updated Encore feet feature a redesigned, tighter fit. They're 1.25mm taller than the original, maintaining compatibility with the original Encore as well as future iterations which will have deeper recesses in the bottom case to accommodate the increased foot thickness.
