Our Hefner is inspired by early 19th Century Gentlemen's Opera Slippers; a masculine trend with a decadent, luxurious feel. Made from beautiful black velvet and black trim with an embroidered gold bee & honeycomb motif vamp. Our slippers are fully leather lined with a flexible black sole. We recommend you take one size bigger for this shape. For example, if you wear a size 6 UK (39 EU) in most shoes, choose size 7 UK (40 EU) for this style. Our size guide is a generic reference for all our customers, and it is based on our customers' experiences. However, because it is generic, there might be some individuals for which it is not representative.
