Solemates. The Marcella is a flat slide on sandal with a square toe. We added a ruched strap to match all your ruched clothes. Fabrications vary by colorway. It runs slightly narrow, so we recommend opting for 1/2 size up if you have a fuller foot.These shoes are lined with leather that’s tanned without chrome or heavy metals. They’re padded with a blend of renewable, plant-based foam, and some of the conventional stuff. So still soft and cushiony but from more responsible sources. We used 80% recycled plastic in our toplifts, and our regenerated leather outsoles are made of 70% leather waste. We like recycled materials because they lessen the water and carbon impact of our shoes, and keep stuff out of landfills.
