In the shoe world comfort and elegance are a winning couple. For this reason Stonefly has started a collaboration with 3M, the well-known American company, adopting Scotchguard Leather Protector for all suade shoes. The treatment doesn't change the natural leather flexibility and breathability but enriches it with unique oil repellency, water repellency and dirt resistance characteristics. Scotchguard creates a protective barrier that time can't change, to repel stains, rain and even mud spatters. Thanks to Scotchguard Leather Protector, Stonefly has harmoniously blended foot comfort, shoe elegance and product quality.
