Routinely cleaning patent leather will help preserve its quality, maintain its shiny appearance, and keep it free from scuffs and scrapes. To clean your shoes, wipe off any dust or dirt with a clean microfiber cloth. Then dampen the microfiber cloth with a little bit of water to gently wipe down the leather. For added shine and to buff out any markings, gently apply leather cleaner specifically formulated for patent leather.

Q&A

Slip-on-and-go style, PERFECTED

Warm-weather style boils down to a feeling of effortlessness that's best perfected with an easy slide designed to be worn everywhere. We used ultra-luxe leather for soft straps that sit perfectly across the foot, while our signature foam padding provides a soft cushion at the insole. A subtly squared-off toe offers up a quiet touch of modernity, turning this slide into your new sunshine favorite.
