Expeditioner's Thighboots ★★★

Taken all the way down to base materials, one Expeditioner's Thighboots is 2 crafting steps deep and needs 2 intermediates — Ramie Thread ×1 and Rubber ×1 — which resolve to 5 distinct raw materials totalling 10 units, plus 8 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 691 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 3 are burned by the intermediates, so the real crystal cost is 3 Earth Cluster, 2 Lightning Crystal, 2 Wind Cluster and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 60, Weaver to Lv 54 and Alchemist to Lv 7 — so no single class can finish it unaided.

3 of the 5 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
