Customer Reviews Smartwool Secret Sleuth

They come up a little higher in the front than I expected. They are still super comfortable and stay on my feet really well!

These are very high quality but are very large. I wear a size 10 shoe so I purchased the large. They will not stay on my heel rendering them useless.

I love how well they stay on and how they keep my feet just warm enough, never smell, and keep my feet dry.

I love my Smart Wool socks so I got a pair for my mom to try. She has narrow feet. I thought these would stay on her feet. Sadly, they don't. They worked the first time she wore them but won't stay on anymore.

I picked up a pair of Secret Slueths because I hate that sweaty-foot-in-a-boatshoe-in-the-summer-but-you-need-the-barefoot-look feeling. They serve their purpose. They are thin, comfy, breathe beautifully, and have a little grippy spot so they'll stay on your heel. BUT! They really need grippy material on the soles so they stick to your foot! The wool is so thin and comfy that my shoes regularly slip and fly right off my feet. They are FANTASTIC for avoiding sweaty feet mess, but become a bit of a hassle to wear. If they just had grips on the bottoms, they'd be perfect.

Even with the grip in the back, they still slide down on the heel.

I love the feel of these socks. They help keep my feet dry. But the heels won't stay on my feet very well. That's very annoying.

They are very comfortable. For certain shoes, the heel part slipped off.

I loved the first 3 pairs and they lasted a long time. Invisible, comfortable, no slippage in the shoe. My replacement order already has done slippage in the shoe, disappointing me.

Good sock, I think. But the sizing is way off. I'm 5.5 and it was way to tight for me. I would definitely recommend ordering a size up for sure.

I bought 2 pairs of the Secret Sleuth and one slips under my heel sometimes when I wear them. The other pair has been fine so far, but I'm not going to buy any more of this style. The Everyday no-show sock by Smartwool is a better fit for me, that one never slips.

In theory these would be great, but they kept slipping on my heel, but they were the right size to not show in a show that has a low profile toe-box, like a ballet shoe. But unfortunately they won’t stay put, so I don’t think I’ll be wearing them again.

The size M feels too small and causes my toes to curl under. I wear a size 8 shoe and M was the size indicated on your char.t I bought a similar sock a few years ago but with elastic all the way around the top. Those have been wonderful and fit perfectly, but that style seems to be unavailable.

Not the great socks they used to be. I have loved the Smartwool socks in the past, but these are not the same quality. They slip and do not fit like the old ones did. They are better than most of the other socks on the market but I was disappointed that they are not perfect any more.

Fit well to "hide" in shoe, but slipped down into shoe just like the more inexpensive socks. Returning

Thicker than expected, simply uncomfortable - returning

I love that Smartwool is carrying no-show socks, but the sizing of these socks is not great. I wear a 7.5 shoe and bought the medium sized sock per the size chart. Whenever I wear shoes with these socks, there is extra material that sticks out in the back. I find that I have to tuck this extra material back in the the back of my shoe. It's great that the backs of the socks where your heels are have a silicone strip to keep them from slipping...but the sizing I found to be too big. The merino wool material is amazing and keeps your feet dry all day...just wish I knew to buy these socks a size smaller. :-/

Everyday inside my tennis shoes

Was really hoping that these socks would stay put on my feet but they quickly slid down my heels. The added heel gripper did not help at all.

I love these socks and would have given them a 5 IF the toes didn't wear out so quickly! I have plenty of these socks in rotation but the toes wear out in > 6 months. I have mended most of my worn out pairs. I think these socks could benefit from a higher poly/wool blend in the toe area. * If Icebreaker or Ibex sold a similar sock I would switch to them in a heart beat. I only wear these because I haven't found another no show merino wool sock on the market.

These stay up better than most but did slide down in my shoes after a while.

I loved the old version - the ones shaped similar to a ballet shoe. The fabric was a bit thicker, and the design was great! I wore them almost daily. I tried the new version a few different times, but they fall off my foot. So so frustrating. Please make the old version again, as I will buy many pairs. My old ones now have holes, and I have yet to find any good no show wool socks.

Please do something with the rear grip to the heel. This sock slips off. I've tried different shoes with the same result. Thanks!

The material feels great BUT I cannot wear them because they do NOT stay on my heel. Constantly slip off - a waste of my money. Trying to figure out how to return them.
