Expensive...BUT....you get what you pay for!
Color: Matte Black, Size: Large
I can't believe I just spent $50 on 4 pairs of socks....BUT..... I have to admit, they are amazing. They fit perfectly, are comfortable and stay on and in place. They are no-show which is just what I wanted. For reference, I'm a 10.5-11 in women's shoe and I got the Large. My one and only complaint is the price....I wish they were a little more affordable.

Worth the Price
Color: Matte Black, Size: Medium
At first, I was unsure because of the price, but wow—I was wrong. These worked perfectly with my loafers and flats. They stayed in place and fit comfortably all day. The only downside is the logo on the back, but overall I really like these socks.

Highly recommend
Color: Cream Beige, Size: Medium, Color: Cream Beige, Size: Medium
These are amazing. I have tried a lot of no show socks and either retired, gave away or threw away. These actually stay up. I’ve worn them with flats and sneakers. They are even comfortable wearing around the house without shoes. I highly recommend these. There are small areas they may show, but it’s not enough to bother me.
