I agree with you that those boots aren't a good choice (soles, heel and the stiching/extra layer of leather), and I am not aiming at beginning a big discussion, but if I read the CRL, I cannot see that they won't be accepted for standard TK approval...only for CEN...
"For 501st approval:
White leather or leather-like, above ankle height, with a flat sole with a short heel, and small U-shaped elastic sections on both sides of the ankle with no buckles or laces. Jodhpur/Chelsea-type boots or an equivalent style is acceptable. Elvis or Mariachi boots are not allowed.
For level two certification (if applicable):
For level three certification (if applicable):
There shall be no seam on the front of the boot (e.g. CABoots are not allowed).
Boots shall be lightly scuffed."
