Using your KIZIK Athens sneakers is a breeze. Just step into them, and the HandsFree Labs® Technology will do the work of springing the heel back into place. You don't have to bend over or tie them every time. For around - the - house wear, they'll keep your feet comfy. On the trail, the rubber traction pods will give you good grip. And for casual Fridays at the office, they look great. When it comes to maintenance, you can remove the insoles and wash them to keep your shoes fresh. Avoid using harsh chemicals on the breathable knit upper as it may damage the material. Also, don't expose them to extreme heat for a long time as it can affect the Rabbit Foam® Outsole.
