Award winning design and a favorite among kids and parents, Extreme is a warm thermo boot full of smart details.
Thanks to a Polyurethane construction with an adjustable cuff lock, Extreme is waterproof, light, and comfortable for all-day wear. Made from a flexible Polyurethane called Elastopan®, which is a 100% PVC-free, it contains millions of tiny air bubbles and is 40% lighter than PVC or rubber. Viking thermo boots provide 2.5 times more insulation than normal PU boots and are twice as durable. With the help of a wool and polyester lining, Extreme can effectively insulate kids feet down to -20°C. The sole of this boot is made from TPU, which is slightly heavier than PU, but has excellent wear and non-slip properties.
For blocking wet, snowy, and frigid conditions, Extreme is a tried and trusted winter classic. Viking Extreme came out Best in Test, in the Norwegian magazine Foreldre & Barn, no 9, 2017.
