I completely understand your comments as AE has made a large number of split toes over the years and currently has several. After looking closely at the toes I began to appreciate the subtle variations in assembly, sole, length of split and style of welt that pushes one shoe into the dressier category and another towards the casual.
So, those seem to be the variables and now you will have far more to consider when selecting several pairs of split toe shoes for the closet. And you likely never wanted to think this much about the subject.
Thanks for the split toe synthesis! This style is definitely not my favorite, but when done correctly...
