On My Own Two Feet (L)

At 10 allowances a run, this leve's 702,370 EXP works out to 70,237 EXP per allowance, which places it 3rd of the 3 Lv 58 Leatherworker Grand Company leves that record EXP. The best of them, Raising the Dragoons (L), returns 326,360 EXP for the same allowance, 365% more.

Across that rung the return runs from 70,237 EXP to 326,360 EXP per allowance — 3 distinct figures spanning 365%, so the wrong pick leaves 256,123 EXP of the allowance unspent.

Nothing above Lv 58 is recorded for Leatherworker Grand Company leves, so this rung is the ceiling at 326,360 EXP per allowance — 11% more than the Lv 56 rung below it.

At Lv 58 this data holds 54 leves paying EXP across 3 categories: the 27 Grand Company ones average 228,371 EXP per allowance, the 3 Fieldcraft ones 1,079,567 EXP and the 24 Tradecraft ones 443,090 EXP, which puts this leve 69% below its own category's average.

Serpentskin Thighboots of Casting ×1 is a Lv 59 Leatherworker recipe, 4 steps deep through 10 intermediates, costing 38 units of raw material and 50 crystals.

Handing that in returns 18,483 EXP and 39 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith, Leatherworker and Weaver.

The record carries a repeats value of 5. This site reads that as 5 further turn-ins on the same leve — an assumption, because the source data defines no meaning for the field — which would put the ceiling at 4,214,220 EXP and 8,892 gil for the 10 allowances it costs, or 421,422 EXP per allowance.
