Silka TV Spot, 'Challenge: Day Two' Featuring Willie Gault

On day two of the Silka Challenge, former Super Bowl champion Willie Gault asks people with athlete's foot to name things they've stopped doing out of embarrassment about the condition, such as going to the beach, taking shoes off or showering at the gym. After he gives them Silka products to apply to their feet, the participants note that they feel improvements, and a doctor says he can already see the medication's effectiveness.
