Not long enough (especially for Propet). I had to take men's size 8 to women's size 8.5. Suitable for swollen feet (velcro), requires XX width (equivalent to 4E or 5E); unswollen width - D. (4E or 5E is used for E-EE. The toe box is high enough and can use a foot orthotic insert over the cushioned insert. Note that the heel is tilted outward, not straight up and down. The Material is also not stiff enough to hold heel well so a bit loose but better with black neoprene than corduroy (see photo) My family member will keep this slipper as it is difficult to put on a swollen foot.Black neoprene can happen for normal shoes.
