Getting started with your Crocs Classic Crush Clogs is as simple as slipping them on. For customization, `Jibbitz™` charms are compatible with the holes on the upper and the pivoting backstrap. To attach, simply push the Jibbitz™ charm through the hole from the top until it pops into place. To remove, push from the inside of the clog rather than pulling from the top to avoid tearing the hole. For care, these clogs are remarkably easy to maintain. Clean them using mild soap and cold water, and allow them to air dry. Avoid direct sunlight or high heat, as extreme temperatures can cause the material to shrink or warp. Do not use harsh chemical cleaners, as they can damage the `Croslite™` material.
