The silicone lining in these socks feels very cold and slimy. I was not able to tolerate the cold on my feet.

Great stuff!
Color: #3 Rose Gold
Trying to give 4.5 stars. It’s phenomenal! My only .5 is that is absolutely does rub off on clothing. I’m going to a party tomorrow and I’ll try using setting spray after application. I love it though. Light weight, no odor and shimmer you can use on body, hair and even accessories!
