The Crocs Classic Crush Sandals are ready to wear right out of the box. To personalize your sandals, simply push your favorite Jibbitz™ charms through the holes on the straps until they snap into place. To remove, push from the inside of the sandal rather than pulling from the top. These sandals are designed for adults and feature a unisex fit, compatible with a wide range of casual attire. For care, simply clean your Crocs Classic Crush Sandals with cool water and mild soap. Avoid harsh chemicals or abrasive materials. Air dry them away from direct sunlight or extreme heat, as high temperatures can cause the Croslite™ material to shrink or warp. Regular cleaning will maintain their appearance and extend their lifespan.
