Men's Dr. Martens April 3 Eye Black Athena Leather Oxfords The Dr. Martens April 3 Eye is a men’s low-top lace-up shoe built with a black Athena leather upper and a chunky lug sole for a more grounded look and feel than a standard flat oxford. Finished with welt-style stitching and a 3-eye closure, it’s a straightforward choice for daily wear when you want durability and edge without a boot height.
