Using these 'KIZIK' sneakers is a breeze. Just step into them, thanks to the HandsFree Labs® Technology, and you're good to go. You don't need to bend over or tie laces. When it comes to maintenance, you can take out the removable insoles and wash them regularly to keep your shoes smelling fresh. For the outside, you can use a soft brush to clean the leather upper and suede accents. Avoid exposing the shoes to extreme heat or moisture for a long time, as this may damage the materials. With proper care, these sneakers will serve you well for a long time.
