    Medium size preferred.
    Size: Large
    I purchased both the large 4" and the medium 3" balls. My 80 lbs German shepherd much prefers the medium size. Show loves to play fetch with it and its lasted well!

    Do not buy these
    Color: Nude, Size: Women 9-13
    These are terrible. They are designed to walk in. The first day I tried them on I walked about 20 steps and they basically ripped right off my feet. I didn’t think much of it and just thought ok I won’t walk in them I’ll just wear them to bed. The second pair that came with the order I wore to bed that night and woke up with holes tore in them. Terrible product

    These are form-fitting and durable. Wearing these keeps the skin moisturizer in place so it can be effective.
