One thing to remember leather was not real popular at sea do to the salty air would crack and stiffin it to the point that it would fall apart. notice that most crew did not wear shoes they most of the time ran around bare foot due to they did not have the money to buy shoes at every port (excluding the Capitan or higher ranking officers hins more share of plunder)
not saying leather wouldnt be out at sea it would be a little more scares then most people would think. so more then likely it would be made of canvis, horn, bone, metal, and wood
