US customs officials have issued a warning to a Costa Mesa street fashion footwear company over a storage feature in the company's shoes. Sha Sha Fine Shoes Inc produces footwear with a 1" X 2" storage compartment or 'G-spot' in the sole of each shoe, intended for keys and or money.Company CEO Billy Ruff states: "The 'G-spot' is a selling feature in some of our shoes. We do not in any way endorse or promote drug use. Hiding spots are a common feature in many shoes, usually located in the tongue of the shoe. We don't understand why we are being singled out. The warning issued by customs makes us sound like we are selling drug paraphernalia.The warning was posted on the front page of the US Customs Service website
