Using these KIZIK sneakers is a breeze. Just step into them, and thanks to the HandsFree Labs® Technology, you don't need to bend over or tie laces. You can wear them for all kinds of activities, from a casual walk to a workout. When it comes to maintenance, the insoles are removable and washable, so you can keep them fresh. To clean the nylon upper, use a mild soap and a soft cloth. Avoid using harsh chemicals as they might damage the material. And remember, the full - abrasion rubber outsole gives good traction, but like all shoes, it will wear out over time. So, if you notice reduced grip, it might be time to consider a new pair.
