Diesel makes great shoes.  They aren't the most comfortable, but they do look great.  I prefer a bit more cushion and heal support.  This shoe can be worn with jeans, work pants, and shorts.  Very versatile.  Very good product.  I don't know if they will hold up for 300+ wear, the sole is a bit thin and I personally wear out souls on most of my shoes within a year or two or (300 wears).
