Suitable only for thick feet! If your foot is of normal thickness, the slipper will be very loose, resulting in strain on the entire system of the sole-toes-ankle in the effort to keep the slipper on the foot. I'm sorry, these are not anatomical, they can cause damage. The problem will not be solved by taking a smaller size!! That's what I did after reading another review that mentioned the same issue.

They are borderline small, the upper part is quite loose on my foot, resulting in the foot sometimes coming out in front.
