This last was unusual in that the cone area was very wide up top, the the 1st change I made was just along the top inside. This is actually V3a, V3b is in the works and will be chronicled next.
I am currently after three aspects of the line; a horizontal take-off from the joint area, a narrow gap to the "under ankle point," and a finish that is not vertical. Even with all these rules the options are many.
The 12E is way too big for me and so I went for substantial changes to get the fit right.
Next is labelled: 12E M2 V3b
With substantial adjustments to the lasts I have made the next trial piece.
