I have pretty big ears and have no issues. Three screws into the rack that get covered with a cap and youre all set. The memory foam is better than other slippers because it bounces back a bit better. The cushion/sole is EVA, or something like it, and is still comfortable. I still do mobile walk around stuff in Quest 2 in a different room. Im always really nervous about ordering shoes online due to my feet being either too big for a 5. I wear a size 11 shoe. Came in the box, plastics and manuals all still sealed and fresh. It is easy to disassemble, and store in the hatch. These will get me through the rest of the spring, but eventually, I will most likely upgrade to something better.
