The Men's derbies Martin 1 from Melvin & Hamilton are stylish and modern lace-up shoes made from leather, which can be worn to work or for leisure. Made of vegetable tanned calf leather and have a leather & rubber sole. Ideal for the fall / winter season, the high-quality leather ensures you will wear them for years. Take care of your derbies by using cedar shoe trees when not wearing them. Shoe trees help prevent creases and wear of the leather.
