Solid-colored warm thermal boots from CeLaVi. The boot has sewn-on CeLaVi logo at the top. The boot is lined with a wool mix which, together with the aluminum membrane in the sole, helps to keep the feet warm. The thermal boots are moulded of the lightweight rubber Megol. Megol is durable and at the same time provides good movement for the child. The thermal boots have deep tread grooves in the flexible bottom, making it easier to maintain foothold. We recommended 1 cm thermal boots as growing room. Inside dimensions in cm: 20 = 12,6 21 = 12,8 22 = 13,3 23 = 13,6 24 = 14,6 25 = 15,1 26 = 15,6 27 = 16,2 28 = 16,8 29 = 17,4 30 = 18,1 31= 18,5 32 = 19,4 33 = 20 34 = 21 35 = 21,9 We recommend washing the boots with warm water and a soft brush. If necessary, they can also be washed in the washing machine at a gentle 30 degrees. As the lining is wool, it is important to dry the boots with paper in them.
