The First Classic Insulated Rain Boot is designed with colder climates in mind, with an insulated vegan shearling fleece lining to further protect against winter chills. Handcrafted from natural rubber, these fully waterproof boots have a flat outsole for stability and a rounded toe gives little toes room to move. Similar to the adults Original Boots, the specially developed tread on the calendered outsole provides grip on all terrains. Able to be worn in temperatures as low as -5C (23F), little feet will be feeling snug and protected on any adventure, rain or shine.
