When you think of an ergonomic or practical shoe , chic might not be the first word to come to mind. So when I was introduced to Kizik and its patented hands-free technology, I was surprised to discover how stylish the brand's slip-on shoes were. Many of Kizik's everyday styles look like any other sneaker (replete with shoelaces and various sleek designs), but their hands-free tech means you don't have to bend down to tie them or hold down the heel or tongue to get your feet into the shoe.
