I ordered multiple different Hammel Dual Surface runner pad sizes for an upstairs hallway.  They help give a low pile rug a lift as well keeps the rugs in place.  These rug pads are a bit pricier than the standard rubber ones but they are worth the extra money.  They come in many sizes and were shipped and delivered within 24 hours.  I'm adding photos of the rugs I purchases so you can see the works of the rug pads.  Note:  the runners are the Brandt Floral Beige/Gray Rug also from Wayfair.
