Glatt, a heroic calculation !
But the answer depends on your assumption about "first nail"
1st leg: 1st nail = $0.01 ... 6 nails per shoe = $0.63
2nd leg: 1st nail = $0.01 ... 6 nails per shoe = $0.63
3rd leg: 1st nail = $0.01 ... 6 nails per shoe = $0.63
4th leg: 1st nail = $0.01 ... 6 nails per shoe = $0.63
Total: $2.52
Time to calculate: 15 seconds
