We can confirm that first meddieval shoes covered completely the feet, by means of ropes and ribbons. They were made with sheeps’ skin or a sort of cloth made of thick wool, usually called ordinary fabric.
Pointed boots, normally made of leather, were worn as a symbol of the huge influence from arabic countries. Boots’ length made reference to the social class of people who wore them, it implied that we could appreciate excessive sizes which made really hard to walk properly.
Boots were made of a huge range of qquality leather, but also in black or natural leather, which one came from cowns, sheeps or goats. For closing them, we could use butttons, ribbons or ropes, however we could appreciate boots withouth any fixation elements.
Progressively, it will be more and more common, the fact of wearing boots which can cover the calf by means of ribbons and buckles.
Men wore boots wich covered the ankle and (sometimes) even the knee.
Lately, there have been modifications in medieval footwear colours, it does not matter if they were in leather or cloth.
The most commons were black, brown, red and green.
