Actually you are wrong Paul.....I went back and looked at the 501st CRL just now and here is the official 501st requirements:
Boots 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.
It later goes on to read:
For level three certification (if applicable): (This would be for Centurion level)
There shall be no seam on the front of the boot (e.g. CABoots are not allowed).
"The 501st approval requirements are listed in black.
FISD Defines two additional, optional levels of costuming excellence: Expert Infantryman and Centurion. In the page below, requirements for Expert Infantryman are listed in blue. Centurion requirements are in red. Please visit the FISD web site for a full description of these standards."
CABoots are not elvis boots (zipper) or Mariachi (weird pattern down the top of the foot)......No matter what...The Caboots Stormtrooper boot is going to be AWESOME in November!
