I've been wearing this type of slippers for at least 35 years. To put them on shoes you need a horn. As soon as they are on their feet, they feel comfortable. I have no idea why the shoes are designed and made to be so difficult to put on, but all I can say is that they will spend a lot of time in the closet.
