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.

Works well for sockless look, but annoying branding placement

Color: Matte Black, Size: Medium, Color: Matte Black, Size: Medium

The Good: works great as true no show socks for loafers. Gives you that sock-less look that many “invisible/no show socks” don’t provide for loafer type shoes. I really like these socks because it works for that purpose and they don’t slip off. The Bad: I hope Ondo considers my review, because although I love the functionality of the socks and would like to buy more, the only thing that prevents me from buying more is that they put their logo right at the heel of the socks. When I’m driving and look down at my shoes, the ONDO branding is very apparent and it’s quite annoying (I bought the black color socks). I’m not buying more pairs because of this one gripe I have with these socks. Other than that, these socks work well. Just too bad the branding placement of the socks is annoying. Will keep my current pairs but won’t buy more.
