Fine choice for smaller dogs
Color: Green-M
A good choice for smaller dogs. My mini poodle enjoys flipping this around and playing tug of war with her humans. She cannot be left with it for any unsupervised play, because she was able to begin shredding one of the straps in a matter of a few minutes. The included pump works great.

Toeless wonders. Love em!
Color: Classic Color
Not gonna lie. These are a God sent when you have an issue with your toes. I hate my toes feeling constricted so these are phenomenal! Comfortable and well worth the money. I also like my socks thin. If you wear boots or hightops, these might not be what your looking for. I do adore the different shades and you can wear them one way or the other as one side is longer. If worn one way, they are higher up the ankle and vice versa.

no toes covered
Color: Classic Color
i love these socks but there is room for improvement. The top and bottom band make indentions when i wear very long. A smooth stretchy bottom and top would be nice. i wouldn’t recommend for diabetics because of the indentions they make. They are fairly comfortable. But if not pulled on right you will walk on the band and it digs in a little. Also after awhile the top slides down and the foot part slides back. i have to keep readjusting. The material itself is soft. I am wearing and i like them but if i want more i will look for some without the elastic bands top and bottom. I dont like socks because my toes are sensitive and i am more comfortable without my toes covered. These are working for me now. In future will look for something similar.

Toes are grateful
Color: Fresh Color
I generally need more toe room in my shoes, but I don't need wider shoes. These are perfect for that. I took off one star because as I wash them , some of the stitching is coming undone. It doesn't seem to make a huge difference, however, so I still wear them. They are way too comfy to give up !
