Metal plate beneath Linothorakes or Spolades

[hoplite14gr]

On the above statue there is banding on his feet and shins also. These are generally interpreted as leg bindings. Why are the arms covered in segmented plate and the feet in bindings? Why can't the arms also be covered in an item of clothing and not armour?

Well considering the existence of this type of armor for gladiators this is an aspect worth examining.
I do not know if i am for or against it but it it an interesting speculation.

Kind regards
