This is a Goodyear-welted product. The upper and sole are heat-sealed and sewn together, not merely glued like many footwear constructions.
A soft, smooth, waxy leather with a medium pull-up effect.
This sole is hard-wearing, with good abrasion and slip resistance.
[Analine] = Clean away dirt using a damp cloth, allow to dry , then use a clear wax based shoe polish to restore shine - if the burnished effect requires repairing then brush the area vigorously with a stiff bristled brush to restore the darker area.
