Bought the wrong size and I missed the return window. I have not worn these outside. These are still listed on the Everlane website. These are 100% bovine upper leather. Very comfortable. I ended up reordering in the correct size because I love them so much. Add a little lift to your step. Laid-back comfort. Our loafer is handcrafted from premium leather and features a true rounded shaped toe, penny keeper, with moc-stitch detailing. Adds an edge to any outfit with a chunky lug sole (plus, it has extra grip and durability). These styles use leather sourced from a tannery rated Gold or Silver by the Leather Working Group (LWG)—the highest ratings a tannery can receive for demonstrating best practices in environmental compliance and performance capabilities.
