Boot Bands made with Opti coils usually fit boots that made by boot companies such as Clarks, Dior, YSL, Gucci. Please look for the letters "Opti" on the slider pull and make sure that it is an Opti "coil" and not Opti "metal" zipper. For Opti metal zippers, the metal size 5 zippers should work.
These Boot Bands are made with leather.
All Boot Band sets include 2 Bands and 4 sliders.
