A barefoot shoe for the cooler half of the year: This is the Denver Leather Men from Xero Shoes. With an upper made of nubuck leather, this casual shoe is ready for anything. While it doesn't have a membrane to keep the weather at bay, well-waxed leather will take you far. Xero Shoes also equips the Denver Leather Men with a cozy lining and a heat-reflective insole to prepare you for the cold. You can also remove the insole when the weather gets a bit warmer or if you're looking for even more barefoot feel. Weighing just 820 g per pair in men's size 42, the Denver Leather is very lightweight and allows you to go through your day carefree. It also features a 4 mm thick dual-chevron tread on a FeelTrue® rubber sole with zero drop – an ideal combination of protection and ground feel.
