The Kigo Shel ($50) is a unisex shoe that's designed for trail running, hiking, and wet weather conditions. Weighing only five ounces per shoe, the thin, high-grip rubber outsole and flexible midsole make it a good option for minimalist footwear. It also has a removable insole that provides extra ground support when needed. Added plus: it's eco-friendly. Kigo shoes are made using recycled materials and water-based glues.
