Pretend to have naked feet.

It will take someone with superlative detecting skills to know you're not barefoot when you  have the Smartwool Women's Secret Sleuth Sock lurking within your zebra-print ballet slipper. The silicone gripper at the heel prevents the fabric from scrunching beneath your tootsies, and the no-show profile means you can wear socks with your flats. The wool and nylon blend mixes wool's anti-odor properties with nylon's durability, and the WOW technology puts high-density impact zones under the toes and heel for a softer step.

My daughter loves these no show socks!

  • Familiarity: I've used it once or twice and have initial impressions

I haven't worn them yet but my career daughter swears by them! They're the best price here at Backcountry.

Smartwool Secret Sleuth

  • Familiarity: I've used it several times

love these socks with my black sandals!!!!!!!!!!! so comfy and doesn't slip at all. cant tell I'm wearing them at all. thanks SMARTWOOL!!!!!

Great socks

  • Familiarity: I've used it several times

These socks are very comfortable, other socks with a thinner border leave deep marks on your skin that after 4 or 5 hours start to ache, that is not the case of these smartwool ones, the border is soft and I did not feel ache after 12 hours.

Great socks

  • Familiarity: I've put it through the wringer

They don't slip, and after you line them up, they don't really show. Very comfortable socks. I got a size small and I am usually a size 6 in most brands.

Perfectly hidden

    I am not a fan of shoes without socks but I’d rather go barefoot than deal with a fashion disaster. These are the perfect sock for slip on shoes. Merino is my best friend these days as you can wear them multiple times before washing.

    perfect for all my low cut shoes!

    • Size Bought: large

    I love these little socks. Perfect for all my boat shoes, vans slip ons, and all low cut shoes that you dont want to wear barefoot (hello stinky, sweaty feet!!!!) but don't want your socks to show. They are nice and breathable, lightweight and stay in place perfectly with the little heel grippers. You need these socks! I wear a size 10.5 shoe and I wear a large in these socks.

    they stay in place!

    • Fit: True to size
    • Size Bought: Small

    Finally a no show sock that stays put! they are super comfortable and they have a grippy rubber strip right inside the heel so the socks stay put all day long! This style goes just over the toe, so they work with a lot of different styles of flats. I wear a size 7 which is right on the border of a small and medium. I went with a small and it works perfectly.

    Wear flats with socks

    Normally wearing flats are hard because you can't wear socks with them. well smartwool has come to the rescue! Not to mention they are merino wool so they dry fast and don't stink!


    • Familiarity: I've used it several times
    • Fit: True to size

    I'm a huge fan of Smartwool socks, and these are a great model to add to the collection! The no-slip heel works great, and the wool is comfortable for all day wear. They do come up a little higher on my heel, but paired with Toms/Sperries/gym shoes, they're still a no-show.

    Best No Show Socks EVER!

    • Familiarity: I've put it through the wringer

    Loved them so much I bought them for my Mom, perfect for everything and Wool which makes them so much more comfortable. Highly recommend.

    My Wife Loves Them

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    Got these for my wife, she is way stoked on them, way more cushioning than would normally be found in a minimal sock like this. They breathe really well and the gripper and more substantial elastic band (than what I am used to) really help them stay in place. Fit seems spot on.

    Air Conditioning for Your Feet

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I wore these little socks dozens of times during 100+ temps and my feet felt cooler than when I would wear no socks. The no-show is the perfect stealthy size for my several pairs of Vans Rata Low shoes. No need to wash after each wear, they don't retain any odor and never feel crusty. Sometimes at the end of an 8 hour workday the elastic would pinch my heel, but they always stayed put.
