I received them and picked up one slipper and put it back in the box. However, it still looks to be a good adaptor. Every click either puts the volume up all the way or mutes. The booties are soft and warm but the sizing isnt good. I bought these to hang some rough-edged painted agates on the wall (see photos). My aging knees won?t stand the stress of tennis anymore but I suspect the 996?s would perform very well on hard surfaces for tennis or for pickle ball. Just peel off the stock pads and stretch these pads on. If you refuse, just buy the small. I am so done being uncomfortable in flat, hard, inflexible, slippery fashion flips. They look nice filled with water.
