And I would also recommend sizing down just slightly. I threw it out as it stunk up the kitchen drawer it was in. Very pleased with this mat. My 2 year old loves wearing them. These slippers fit perfectly. The earbud part doesnt slip and fall out every 5 seconds. The material was good quality and did not wrinkle easily. It also has a rubber pad at the bottom so it doesn?t slide on the desk. The only problem I had with it was the box it arrived it. This indicates a rush in the manufacturing process.
