XDR Outsole
Definition
Extra Durable Rubber — a harder, more abrasion-resistant outsole compound used by Nike on outdoor and basketball shoes designed for rough surfaces. XDR outsoles last significantly longer than standard rubber on concrete courts.
In Context
“If you hoop outdoors, get the XDR version — regular outsoles get chewed up on concrete in a month.”
