I have tried every single No show sock you can imagine and I was getting tired of buying socks I thought were good and boom, a drawer full of bad socks. Im at the age when I am still young enough to wear them, but remember a time when you could wear your Vans, Chucks and other sneakers without socks (or anything) and eventually then got that weird smell and you had to throw them in the wash (Behind your moms back of course). Now, I have tried the sports ones (So you really wants Adidas or puma on your socks? too thick, the thinner one had crappy elastic that didn't last, or they were too small after the wash. It's bad enough when you lose socks, but when you lose them when they are too small and have to stretch out like a ladies sock, no bueno. Invisasock came to me by accident. I use to fly a lot and was always in the airport and had to always take off my shoes, even when wearing sandals I refuse to step on the ground at the airport or anywhere public, just nasty. So I would always carry a pair of socks in my bag. One day I saw a guy ahead of me take off his shoes and stepped on the ground, but you could not tell at ll that he had socks on. I asked him where he got them, he gave me the link and the rest is history. Now I am the one telling everyone where to get them in similar situations. 5 stars - the best sock ever. If you have had them for a couple of years or so, or have many from different years and they feel like they're slipping- THROW THEM OUT and get another few dozen. After 2-3 years they did their job, time to buy new ones. They are in such an excellent price point that you can buy a few dozen in 2-3 colors without breaking the bank. A quick tip, if you cant throw them away, then use the old ones at hone (if you're walking barefoot inside your house, gross, put some slippers or socks on) or you can put them on when you cleaning something (make sure they're clean) then when you destroy them and you can justify tossing them, then you're good. But seriously- They are honestly he best no show socks ever - like ever
