Dog loves it, but it comes apart pretty quick.
Size: One Size
The dog loved chasing it and playing tug-of-war, but it lasted less than 30 days. If the outer rubber portion of cover was thicker, or all canvas material, it would probably last for a few months of rough play. May buy again if I can't find something similar to try.

Comfortable toeless socks
Very soft and comfortable. However, the elastic is too tight. Should be wider so circulation is not cut and you are able to wear it at night. Therefore, is not good for diabetic and heavier people. Larger sizes should be available.

Terrible Quality, fell apart
Very poor quality. Came apart after one washing. Unraveled. Would not purchase again. Wish I had not purchases the first time.

Socks
They fit okay and they're comfortable but the only problem I've been seeing is that they're starting to unravel at the toe end
