Flexible and breathable, the Nike SB Chron 2 is a worthy successor to its predecessor. The updated design includes a redesigned shoe collar and heel as well as recycled materials in some crucial places - while maintaining the same level of comfort and the performance you know and love. Suede and canvas are durable and breathable. Recycled materials have been used for the laces, lining and swoosh. Foam padding with every step. The upper material is vulcanized with the sole, giving it a flexible feel. Extended toe protection ensures durability.
