The Boomer is designed in a classic, neutral base colour with a contrasting inner and branding for a subtle yet eye catching look. The Uppers are engineered with Flexiknit technology – that is, they are seamless, flexible and hug the foot for a natural sensation. These uppers expand and contract with the movement of your feet. The soles are designed with Athlite technology that makes them the lightest soles in the world. The Boomer is comfortable and ultra light, and meant for enhanced performance.
