Toes are grateful
Color: Fresh Color
I generally need more toe room in my shoes, but I don't need wider shoes. These are perfect for that. I took off one star because as I wash them , some of the stitching is coming undone. It doesn't seem to make a huge difference, however, so I still wear them. They are way too comfy to give up !

They fray and unravel after a few washings.
Color: Classic Color
They are exactly what I needed but after a few washings they started to fray and unravel. Also I was looking for black and had to buy the 4 different colors.

Just what I was looking for

Great quality for the price! Use them for my pedicure clients in the winter. Would like more cute styles though. Would recommend!

Terrible
Color: Fresh Color, Color: Fresh Color
Should be a zero! Would be shocked if these are cotton at all! Feels like polyester, unravels after one wash in a lingerie bag on handwashing—horrible!!!
