Let's get real about leather and the environment. REEF sources our premium leathers from eco-aware tanneries. Plus, the midsole of this sandal is made with 51% renewable sugarcane-based EVA instead of petroleum-based. So when you wear the Drift Classic, you'll have peace of mind as well as incredible comfort. A full-grain leather footbed features high arch support, and soft leather on both the top and seamless lining of the straps literally hugs your feet. Good vibes with this one.
