Swedish footwear brand Tretorn has treated us to minimally-designed, high-quality tennis shoes and rubber boots for over 120 years. Regarded as the first luxury sports shoe, the brand's iconic Nylite was a tournament favorite in the era when tennis stars made rock stars blush. The Official Preppy Handbook made it immortal in the 1980s, calling it a must-have for the American prepster. The Swedes have stayed true to their Scandinavian design ethos with the latest addition to the Nylite pack -- this gray linen colorway with leather laces. While the materials scream luxury, the end result is equally laid-back, pairing perfectly with your summer weekend wardrobe.
