The PUMA Women's Mostro Fey Satin 'Black' delivers a sporty interpretation of a Mary Jane shoe, featuring elements from the unique track-meets-surf aesthetic of the original Mostro. Shiny black satin is utilized on the upper, secured with an elastic strap and accented with a lateral-side Formstrip. An Ortholite insole provides lightweight cushioning. Underpinning the slip-on is a spiky black rubber outsole.
