I first purchased these for my husband, whose feet are always cold.  No other "slipper" has kept his foot this warm.
He has a high arch and he is easily able to fit these boots on, whereas he has had problems getting others on.
They are lightweight and are his new travel companion.
Nice anti-slip material on the bottom.
There is no arch support, as would be expected in slippers.
I just purchased these for myself and I am very pleased with them.
