    Wouldn’t buy again
    Style: dog ball launcher
    Compared to the namebrand thrower this one sucks. It just throws the ball way up in the air.

    🧦 Simple & Effective – ZenToes Moisturizing Socks Review ✨
    Color: Green Gingham & Multi Plaid, Size: Regular
    These ZenToes moisturizing socks are such a smart and effective solution for dry, cracked heels! I really like that they only cover the heels instead of the whole foot—no hot, sweaty toes, which is a huge plus. They come in a pack of two, and for the price, it’s a great value. I also found that they fit well and stayed in place overnight. They were a bit snug around my foot, but still comfortable enough to wear. What really impressed me is how well they work. The socks are nice and thick, and after just one use overnight, my heels were noticeably smoother. Even better—the results lasted about a week without needing any extra lotion, which I personally love since I’m not a fan of applying creams. I would definitely buy these again and highly recommend them if you’re looking for an easy, low-maintenance way to keep your heels soft.

    They work!!
    Color: Fuzzy Slate Gray, Size: Regular, Color: Fuzzy Slate Gray, Size: Regular
    I bought these to replace a very old pair that I originally got at Bed Bath and Beyond like 20+ yrs ago, and the fabric was starting to fray. However, the gel pad inside (at the heel) was still working just fine. Anyway, this new set includes 2 pairs, with a gel pad inside each heel area. Results are truly amazing, I kid you not. You can use them without a moisturizer, but I like to put moisturizer on my heels, then wear these overnight, and in the morning my heels are soft, with no dry skin and NO cracks. I like the fact that these are kind of soft and fuzzy (outside), but I LOVE that they leave your toes exposed and cool (because my heels feel kind of warm from the moisturizer and gel pad). They are of good thickness, and I feel they will last a long time (of course remains to be seen). Highly recommend.

    Perfect for cracked heals ♥️
    Color: Cheetah, Size: Regular, Color: Cheetah, Size: Regular
    These are thick not cheaply made, has a nice texture inside the heal area which I love. I wear them at night after I apply Aquaphor to my heels & while sleeping they are very comfortable. I slipped these guys on & my heels are healing so much faster no more cracked heels for me. 😃 I highly recommend them.
