Its hard to explain what i mean, I've attached a very very poorly made visual aide done in MSPaint by yours truly! I'm thinking create two matching cakes. Pointe shoes do not differ from right to left foot, so they can be identical. Then cover them in fondant and emboss/color/paint/luster to your heart's content. The section I've made yellow, I'm thinking cut out a wedge of that cake the same width as the other cake, and remove it. This will leave a slope from the middle of the shoe outwards, as opposed to a "hole" in the cake. Then position your second cake into that hole and dowel them, or if you don't want to break the fondant, dowel the first one and nestle the other cake onto the dowel (only if you're sure of your measurements). Then attach ribbons. Depending on the size you've made them, they could serve the whole amount, or you could make them smaller (think loaf pans) and then then place them atop a larger cake. HTH!
