X Proenza Schouler Arizona Leather Slides

Birkenstock's popular black Arizona slides are curated by Proenza Schouler designers Jack McCollough and Lazaro Hernandez, who found inspiration in utilitarian workwear and athletic footwear to create a striking, yet pragmatic look. They're made from patent leather framed with white topstitching and rest on the signature moulded insole and a ribbed rubber sole. Adjust the Velcro straps to ensure a personalised fit.
