Gaffed Shoes The most common of all the gaffed shoes is the1.prisni shoe, or second dealing shoe. With these shoes, the top card can be pushed back slightly and peeked by looking into the prism. Prisms can be built into baccarat shoes with translucent lids, and even opaque lids with modification,, that allow one to peek the top card. These prisms can also be built as part of the faceplate. In other words, there are no additional parts to the shoes basic structure, and are currendy sold as an all-transparent shoe. With some very sophisticated, innovative, optical engineering, this kind of peek is also possible without the traditional prism.
