I saw these and instantly thought they would be amazing! I was hoping for just that. I received them today and tried them right away. I love the gel feel but im not really liking the way they kept rolling off. They're a bit too small id say and when walking they roll off from the back. I didnt think my foot was other than average? Maybe? Im a size 7 in women's shoes.

Super Awesome

I have the driest feet, my mom did too so I should have known that I would inherit it as an adult myself. My toes literally crack and split open from dry skin, I call them fissures. They really hurt. Last night I used my cheese grater foot file gently on my heels and calloused parts, and then applied liberal lotion, and wore those squishy socks all night. I woke up to the most moisturized youthful feet I’ve ever seen attached to my body! Wow these totally work!!! I even slept better than I have in a very long time. I’m very pleased. These did exactly what I hoped they would do.
