ZeroSock Bamboo Viscose Ultra-Low No Show Socks (4 Pairs Per Box)

They look to be of a good quality material, they wash and wear well, they generally stay on the foot ( they are slightly looser after the first wash) I bought the largest size because often socks run small. My foot is 11.5 inches long there is room to spare (maybe a couple inches ) but I do not think I would have been better off with the smaller size. If the length of your foot is no longer than about 13 inches they should fit fine if your foot measures longer than that they might feel a little tight. I rated a 4 because I tend to wear without shoes a lot and they sometimes slip down since the first washing ( not often) but as I stated mine are just a little bit big for me but I choose a little big over too small. The actual fit is quite good.

So I have one single sock out of this whole pack that just refuses to stay up on my heel. The rest work just fine. No show, comfortable, good to go. Except that one guy, who keeps slipping down under my foot when I'm walking, driving me insane. Other than that, would have given 5 stars.

These are great socks. My issue with other no show socks is that they still show with shoes like loafers. These are much better in that regard. My only issue is there is still some extra material at the heel and you kind of have to put it on a certain way for it to now show. But does not slip off for me.

Struggled like most to find a sock that was a true no show. Saw these and thought why not. Work great, true no show, and yup good enough for a guy too. Don't care what others think, my feet are comfortable and walking in feel good on the feet. Would definitely recommend and buy again.

2 pairs fit perfect with no slip, 2 pairs didnt. One sock of each of 2 said pairs slipped fairly quickly and I couldn’t make them work. Theoretically I got 3 pairs out of 4. They are comfortable and def no show as advertised. Just listing above for awareness.

Update: I contacted zero socks customer service and they happily and quickly mailed me another 4 pack of their ultra low loafer socks to see if the first order was the wrong size or something. Sadly, they would not stay on either. It must be the shape of my foot or maybe that my shoes are slightly loose and pull them down. Actually, I tried them with another pair of tighter loafers and although they lasted a little bit longer, it wasn’t by much. I wear a men’s size 9. Online, it said that was a medium, which is what I ordered. Both times the box said men’s small. The customer service rep assured me that was the correct size for my size 9’s and they seemed to fit just fine. But for whatever reason, they quickly fall off my heel and are therefore useless. But as I stated below, I love their super lows and will buy them again. I quess I should have put this update AFTER the below so you get it in sequence. Oh well 😎.I was so impressed with the four pack of super lows that I bought a four pack of ultra lows to see if they were truly no show socks. I also bought my wife a four pack. I am so disappointed. The socks fell off my heels within minutes of walking around the house. I love the other set of super lows and thought I would get the same result. But they failed on their most important function: Staying on my foot!!! They’re useless and I’m returning them. I don’t know what went wrong nor how they could be so bad. I guess when you get socks cut too low they won’t stay on. I’m sure other feet will have different results, but these just didn’t work for me at all. Also, they also show a bit at the corner made where the tongue of my shoe meets the side. They show less than the super lows I bought, but they do peek above your standard penny loafer by maybe a quarter inch just at that one spot. And a tiny bit at the heel too. I’ll stick with the super lows moving forward.However, the ultra lows that I bought my wife fit fine and do not slip off her feet. She loves them, so go figure. I wear a men's size 9 shoe and bought the mediums. The super lows are great and stay up but the ultra lows do not. They slip off my heel within a few steps. Maybe I need to order smalls or it's a bad batch or who knows. But I can't wear them so back they go.

good quality Ultra-Low No Show Socks.

I'd been looking for a quality no-show socks with silicone heel tabs so they won't slide, and that didn't cost $10 for one pair. I've tried probably every pair on Amazon, and these are probably the best quality, albeit on the thin side (go for the Leotruny brand, if you want something thicker and more on the athletic side, but that still doesn't show). These work well in canvas Sperry's, white low-top K-Swiss or Converse, and probably any loafers.
