Nope - All RTW
Heel height is the same.
724 last is definitely more angular. It is also slightly wider (but slightly shallower) in the toe box, compared to the 1966 last.
I personally like 1966 last better since it looks sleeker (and the lines smoother) in my opinion. For me, fit is almost the same. I do not notice any difference
+1. Thanks for your input
