great concept, just one tiny annoyance...
Color: Black, Grey
i love that a sock that lets your toes be free is even a thing that exists. i love that this company was started by a young girl, now turned young businesswoman.
i have pain in my big toes, so i can't wear close toed anything, but feet get stinky if you wear shoes/slippers all the time without socks. this is a great solution.
the only thing i find slightly annoying (not enough to stop using these) is the seam on the bottom of your foot, near the base of the toes. it is a straight line, which is fine on the top of the foot, but i wish the bottom itself curved a bit, to follow the line of the toes. as it is, the seam lands right in the middle if the ball of my feet, so i can feel the seams everytime i take a step. i am constantly pulling the seam toward the toes, to try to keep from feeling it, but then my pinky toe gets caught and balled up on the inside.
outside of that slight annoyance, they're comfortable and fit well.

Good fit
Color: Black and Gray Argyle
I wear a size 9 shoe and these fit well. They are a little snug, but not too tight.

A little expensive but really come in handy!
Color: Black, Grey
So far I am really happy with these socks. I broke my big toe and had to have my toenail removed and am wearing a post-op shoe/boot.
I wanted to wear a sock underneath so that my foot wouldn't get too sweaty but my toe is still too tender for regular socks and cutting the toes off of regular socks doesn't work because they won't stay put.
These work great- I actually pull them up over my little toes and just leave my first couple of toes exposed. I really like that you can wear these on either foot (unlike some open toed socks that have openings for the big toe and the rest of your toes so they are designated for left and right foot) since I'm only using them on my right foot.

Excellent idea, could be better executed
I love the idea, but my problem with this product is that the bottom of the socks are made too short. The socks tend to slouch up when you wear them for awhile, so the entire ball of your foot will be exposed at some point. I would like to find a pair that cover the ball of the foot as well. But the socks are well made and attractive.

Perfect Solution for Moisturizing Heels Without Full Socks
Color: Black, Grey
Excellent quality and incredibly soft! These toeless socks are perfect if you like to moisturize your heels but don’t want to wear full socks. They stay in place and keep the lotion where it needs to be—highly recommend
