    A clean, white sole can make your ultra-boost sneakers really look good. Because they are soft and spongy, boost soles can pick up a lot of dirt and may eventually turn yellow.

    Learning how to clean & whiten your sneakers is a badge of honor.

    Easily Remove Yellow Stains From Shoes!

    Flex+ Shoe Boost Whitening Pen

    This flex+ boost whitening pen is formulated specially to treat and restore yellowing BOOST midsoles and bring them back to life using a specialized paint. It is also perfect for tidying up marks and blemishes on your midsoles to get your shoes looking like new again.

    Acrylic-based, waterproof, & durable

    The water-based acrylic paint inside this flex+ pen gives a flexible & waterproof layer of the painting surface. This pen uses the best formula specifically designed for boost foam preventing cracks over a period of time.

    Easy to Use

    This boost whitening formula is very easy to apply as it is in pen form. It can be wide or narrow tipped and is perfect for use with every detail providing a tidy finish even on tough to paint areas.

    Pump Action System

    A pump-action valve system has been created to offer the user a superior quality & adjustable output. It is designed for optimum flow control. No mess or leftover paint after applying.

    Widely Used

    How to Apply
    • Shake well before use

    • Allow drying for 30 minutes
    • Repeat the process with a second coat
    • Apply more coats if necessary
    • Allow to completely dry for 24 hours before use
