Maybe it is built for Shaq. Good sole for running and playing. Love the color & fit. I bought these for portable use with my Pixel phone and I use a Meizu dac/amp dongle. This brand will probably now be my go to for slippers! I was very frustrated when some applications or websites wouldnt scroll down. They are a little big for my sons’ heads and slip off quite a bit but doesn’t seem to bother them much. Finally, DJ style headphones with large enough ear pads! Otherwise, this is a great product and still get 5 stars from me. I love having the shoe pocket on the outside, its plenty big enough and the mesh our pockets on the outside are large enough to fit a wide water bottle, but I"ve also put my cell phone there with no issues.
