Be aware! Once they are on, do not walk! 😂
Flavor Name: XL silicone socks 2 pairs
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.

Best possible option out there!
Color: Large - Obsidian Oasis
Fits like normal sock for me. I'm a guy.... Fits like ankle sock I got large. I wear size 9.5 to 10 USA show size. How that helps. It fits just like a normal ankle sock doesn't restrict or press on your toes like others. Woke up this morning and my feet don't look like all peely they are normal looking now so that's good I guess? They work.

Gel socks
Color: Purple Paradise
These feel really weird to put on but once they warm up a bit they’re not bad for just laying around and relaxing. Definitely be careful walking around in case they slip against your foot. I’m not really sure I felt any softening or moisture difference from the oils supposedly embedded in the gel, but they do give your feet a bit of humidity which I guess helps when they start sweating lol. I wear a size 8 in women’s shoes and they felt like they could still be stretched much larger, but if you’re just laying down they don’t need to be snug. If you have anything smaller than a 7 they will definitely be long and floppy. The purple color is pretty and they are soft on the outside. I’m not sure about durability yet since I haven’t washed them yet but they are hand wash only so I expect they would last a while if you don’t over stretch or damage the gel inside. They seem to be constructed fine, the socks aren’t coming apart or unraveling at all, I’m sure the gel helps the soft fibers stay together as well
