Crocs Retro Clog Retro is the shoe to be seen in... A little funky, a lot of fun. It's the iconic Crocs Clog re-imagined as a 70s-inspired track shoe. With its lower profile and track-inspired design, Crocs Retro rekindles the spirit and fun of the original clog. Crocs Retro has a herringbone rubber outsole for better traction and sidewall stripes to make you smile. The best part? It has the Crocs feeling inside!
