The Norwegian welt is a practical sturdy construction with an additional stitch row through the welt to fortify the join between the upper and the sole. Despite the sturdy look, we've used the Finproject Extralight sole; cleated and durable, but so much lighter than it looks. We've chosen a deep burgundy, hi-shine calf leather with great water repellent properties for the Derby upper and included a full leather lining and insock.
