The sandals are quite rare, so they'll probably take a while to sell. You should (if possible) do some advertising (let ppl know, post on server forum if any etc) to get the word out. Your typical 75BLM isn't going to be interested in them, but a real BLM is going to want to get their hands on them. They're currently the best feet for BLM drain/aspir.
The thing about pricing is that recently the union update added the NM item drop to the list (Harajnite shell) so they're starting to be seen more. I'm not sure how rare the drop rate is but form the NM side of things it's still very rare. I'm no crafter but I would probably do something similar to Genie Weskit's pricing. Probably not 3mil but maybe 2~2.5ish. Ask some of your bonecrafting friends? >.>
Congrats btw on the synth^^
