Comfortable. Period
They are comfortable which is most important for this item. If they’re not comfortable, you’re not gonna wear them but these are comfortable. They fit well and they don’t squish your toes cause they were open. I recommend them.

Great traction on bare floors and no sweaty feet!
I love to wear these with sandals -your feet won't sweat or slide around and you can still show off your pedicure! Great colors also and good value for the price. I did take off one star because one pair (grey)had two left feet!
