My Heels Were in Bad Shape. Like… Really Bad
Color: Gray
These moisturizing heel socks with the gel cushions were honestly a small miracle for me. After recovering from cancer treatments, my skin became extremely dry everywhere, but my heels were the worst. They cracked so deeply they looked like fissures and were even bleeding. I tried lotions and bandages repeatedly with very little progress. A friend suggested I treat my heel like it might have a fungal component, so I applied Lotrimin cream, put these heel socks on, and hoped for the best. Within three days, my heels were fully healed. I completed a 7-day routine, and my feet have never been softer. The silicone gel cushion is comfortable, soothing, and stays in place. I loved it so much that I still treat myself about once a week, even though I really don’t need to anymore. They are also washable. I hand-washed mine in the sink and let them air dry, and they came out looking brand new. If your heels are cracked, painful, or need serious care, I highly recommend these.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

Flawless Finish & Fantastic Value
These blenders are a total game-changer. The quality is fantastic, they are incredibly soft, bouncy, and provide a seamless, smooth finish for my foundation. I was also impressed by how well they handle powder for setting. Getting a 6-pack is an unbeatable value for the quantity. I am officially a fan and will definitely be purchasing these again!

best makeup sponges on the market....even better than the $20 ones
best makeup sponges on the market....even better than the $20 ones. super soft, even coverage, doesn't absorb too much product & extremely affordable for a multi-pack so you can start throwing away your sponges when they go bad instead of hanging onto them for concerning amounts of time
