How to use: Simply step into these KIZIK sneakers, and the HandsFree Labs® technology will do the rest. No need to bend down and tie laces. They're perfect for a quick and easy start to your day. Attention: Make sure to choose the right size to ensure a comfortable fit. The roomy toe box gives you plenty of space, but if your feet are wider, you might want to size up. Maintenance: The removable and washable insole can be taken out and cleaned regularly to keep the shoes fresh. Wipe the stretch canvas upper with a damp cloth when it gets dirty. The full - abrasion rubber outsole is durable, but avoid wearing them in extremely harsh conditions to prolong their lifespan.
