Love the size variety off his pack. The foam pads feel great on your feet. I do find shreds of the rug fibers all over on a daily basis. Some may be from my dog scratching and loosening them. But it also happens with normal foot traffic. One of the rugs is next to a door, so every time the door opens over it some pieces get loose as well. I love them though, I just hope they don't go bald!
