Norman Vilalta Review | Calder Wingtip Derby Shoes In Brown Calf。PORSCHE DESIGN Made in Italy Leather Square Toe Derby in Chocolate Brown Retail $595 Around 300. That’s the number of steps required to transform premium box skin leather into the Porsche Design Nappa Lace Up derby. The traditional Goodyear welt construction results in a leather shoe that provides flexible support for the complex movement of the foot – and that can be worn for a lifetime. The breathable cork filling between the insole and outsole adapts to the contours of the foot and creates a form-fitting footbed. Insoles in this shoe are made in a traditional ground tanning process in deep pits lined with tanning agents such as oak bark and fruits. This environmentally friendly process results in exquisite leather graining and a warm, woody tone – and it imparts the unique properties that make the leather gentle to the skin, water-repellent, breathable, moisture-absorbing and hygienic. A business shoe that truly does it all. Size 11 2 E Condition Very Good to Excellent 8-21252.3A
