Just okay
This didn’t last a day. Not for a large dog. Just medium size or small dog.

Good size
Easy for the dog to grab one of the tabs. She likes playing with it outside.

My boy love it
My dog's favorite toy. It's really the only thing that he will chase after. I keep buying a new one every year.

Nice quality! BF approved.
Size: 9, Color: Olive
I got these for my boyfriend and he loves them. The color green is really nice and the quality is really good. I would recommend doing a waterproof/weather treatment to them if you plan to wear them outside. His got water marks on them already and I didn't treat them.
Important note: If you have narrow feet these will work great, but if you have wide feet it might be an issue. They are true to size.
