Classic yet highly versatile rubber boots with a removable, warm wool lining. The boot is made of recyclable SEBS rubber that is PVC free and very lightweight. In addition, the boots are machine washable at 30°C. The wool mix lining is removable for drying at room temperature, but do not tumble dry as this can result in shrinkage. Return the lining to the boot once it has dried properly. Because rubber is not a breathable material, the boots should be allowed to dry out thoroughly between each use. Guaranteed fluorocarbon free. NOTE: Runs small, think about ordering a size larger than their shoe size. Weather Defense: Warm and waterproof Versatile: Wear with or without wool insert Pro Tip: Complete your winter boots with a warming wool sock. Value: Boot should last at least two years. Removing wool insert provides extra room for growing feet! Sturdy: Well constructed boot keeps kids stable Easy Care: Wipes clean with sponge cloth Reliable: Kavat has been making boots in Sweden since 1945!
