Whisperfine Woolen Boots ★★★

Taken all the way down to base materials, one Whisperfine Woolen Boots is 2 crafting steps deep and needs 2 intermediates — Ground Sloth Leather ×1 and Sewing Thread ×1 — which resolve to 4 distinct raw materials totalling 10 units, plus 22 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 695 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 7 Lightning Crystal, 7 Wind Crystal, 4 Wind Cluster and 2 other kinds.

The chain crosses two disciplines — Weaver to Lv 70 and Leatherworker to Lv 70 — so no single class can finish it unaided.

1 of the 4 raw materials matches a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

Of the intermediates, Ground Sloth Leather has the widest use: 44 recipes call for it, spanning four of the eight crafting classes.
