I absolutely love these things. But the first time I put them on in the living room. The walk to my bedroom was VERY interesting 😂😂😂 I now know I need to put them on and hang out for a bit, or simply go to bed. They do exactly what I need them to do. Feet feel great afterwards! With the right lotion, only need to use one every couple of weeks.

Transformed my feet

Flavor Name: XL silicone socks 2 pairs

After trying several other brands that actually my size did not have the luxury feeling of these. T although x large they have the BEST feel and function. I put lotion on then slip them on and within a few minutes my dry cracked heals are soft. Really a nice product.

Fun but kind of lower quality

I like this stuff but it is a little to oily for me. It has a soft baby powder like fragrance. When I look at this I would think it would be very glittery but it really isn't. It gives just kind of a subtle shine almost like a suntan oil. It would be really fun for like at a beach or something like that. I would like to give this 3.5 stars. This product has it's place and time but this doesn't work for a daily driver.

Absolutely not

This is a sticky mess. There are three important factors to consider when testing any body glow/glimmer product: 1) Is it comfortable on this skin? 2) Does it actually give the desired affect? 3) Will it stick around while you're outside living your best life or will it fade into nothing? Well this sticks around, all right. In the worst way possible. But it's not comfortable and it doesn't look good. It's just sticky and gross. Almost no perceptible shimmer or glow. I couldn't see it at all but I could definitely feel it clinging to my skin. I had to shower just to get that feeling off of me. Hard pass
