"The 1600 has so much cross-over appeal. It's great for a workout or with a pair of leggings and is really lightweight.” – Heidi Klum
A competitive running shoe, the 1600 has been chosen by Heidi Klum to be part of her HKNB line, with colors she has chosen and form and function she approves. The HKNB 1600 features a blown rubber outsole, synthetic upper with breathable mesh, and an iridescent "N" logo. Designed to provide a glove-like fit the 1600 is for the runner who's both serious about running and serious about looking good.
