Lightweight and with midsection protection We love the Helly Hansen Cascade Mid-Height Hiking Boots when we travel quickly with a light backpack. Helly Power-Stride midsoles are made from lightweight EVA foam for cushioning and the Helly Tech membrane provides breathable, waterproof performance for wet roads and inclement weather. At just over £2 a pair, the Cascade weighs less than regular hiking boots and features a host of Helly Hansen's patented technologies to boot.
