3,108. Shaatnez Slippers

Hilchos Kilayim 10:14

Rules similar to those in the previous halacha apply to shaatnez drapes. Soft ones are prohibited out of concern that one might lean against them and they will wrap around him. If the material is firm so that this can’t happen, then they are permitted.

Hilchos Kilayim 10:15

One may wear a backless slipper of shaatnez. Since the skin of the foot is rough, it doesn’t derive benefit like other parts of the body.
