Very comfortable
Size: 3X-Large, Color: Chocolate
Ahhhh! I think I found my slippers! They are wide enough, long enough, sturdy enough and comfortable. I might even buy a second pair to have handy.

Favorite toy.
Seems to be of good quality. There are probably a dozen different name brands for these balls. Our puppy loves these. Our son’s 90 pound golden lab has had one for a couple years. He has his outside and it’s a very similar design. Although not the same manufacturer.
