Boots?
Note that the French Pilgrim was not wearing boots. He was wearing sandals!
i walked the Way in sandals, too and found them considerably more functional than heavy leather boots. The mud was a drawback to them, though, as was the numerous piles of cow droppings in Galicia. Perhaps that was even worse, but I could clean them (sandals, feet, wool socks) at any stream or even puddle just by walking through it a few steps or so. The Camino is mostly a comfortable walk so one should choose comfortable footwear to do it in. It is tough to go more comfy than a great pair of hiking sandals!
