Using these KIZIK sneakers is a breeze. Just step in, and you're ready to go without the hassle of tying laces. They're suitable for both men and women, so anyone can enjoy the convenience. When it comes to maintenance, you can easily remove the insoles and wash them to keep your shoes fresh. The nylon upper can be wiped clean with a damp cloth. Avoid exposing the shoes to extreme heat or harsh chemicals as this may damage the materials. These sneakers are built to last with a full - abrasion rubber outsole, but still, be gentle when walking on rough surfaces to extend their lifespan.
