These boots require no complex setup; simply slip them on. They are compatible with Crocs Jibbitz charms for personalization. To care for your Crocs Classic Neo Puff Boots, gently spot clean the uppers and lining (68% polyester, 32% EVA) with a damp cloth and mild soap. Allow them to air dry completely away from direct heat or sunlight. Avoid machine washing, tumble drying, or using harsh chemical cleaners, as these can damage the materials. The 100% polyester cushioning and 55% rubber, 45% EVA sole are designed for durability with proper care.
