Would this pair of sandals be good for my Greek impression?

[ouragos]

They have a raised heel - which is wrong. They have a buckle - which is wrong. The style is sympathetic, but nothing more. I would warrant a good guess that the sole is synthetic, which is wrong .... between the 5th and 4th centuries there was a shift between having a toe cutout and not having one - so is you are trying to go for a 'classical' hoplite and an alexandrian representation as well, but only have one pair of footware I would suggest an earlier design?
