Product title: Sanuk Men's Chiba Slip-On
Product description: Alright grasshopper, if you can snatch this sidewalk surferer from our palm, you shall finally become a true master of comfort., Sanuk was started by surfers in southern California in the late '90s who were looking for footwear that reflected their lighthearted way of life. Founder Jeff Kelley was disappointed to see little selection in a category of footwear that had become his main shoe staple: the flip flop. Jeff had always been interested in footwear and with a little help from a few friends Sanuk was born. Years later, the Sanuk brand still delivers out of the ordinary, quality product to surf and specialty shops every season and has helped bring the flip-flop category from a summer only item to something worn all year.
