Disappointing
Not what I was hoping for. I have a size 11 foot, so they fit fine. They are difficult to walk in and if your balance is bad, you run a high risk of falling. I wear mine at night so the majority of the time it is fine until I have to get up in the middle of the night

Serves its purpose
If you can get past the texture of the silicone these will work wonders for your feet. There’s no odor, easy to put on but they are cut small. There’s no moisture it just feels moist because of the silicone. They are very soft and durable.

Dissatisfied
Didn't like the socks at all. The silicone in them made my feet sweat and couldn't wiggle my toes at all.
Gloves were okay, received them with holes between the fingers, only able to wear each twice.

too small
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.
