"The lighter sister of our Ribelle HD, the Ribelle Lite HD combines the efficiency and agility of the Dynamic Tech Roll System with a lighter, more flexible upper. The DTS system features an improved rocker profile under the sole of the foot that increases notably the efficiency of walking, adding considerable energy savings during long days in the mountains. The dual-density PU midsole and the Vibram sole inspire safety when tackling technical terrain and the fully synthetic upper is supported by a breathable membrane waterproof HDry, which provides protection and support for heavier loads on rugged mountain terrain. The Ribelle Lite HD truly sets the bar for lightweight mountain footwear. 37.5® TECHNOLOGY 37.5® technology lining material absorbs moisture more effective for drying quickly and improving thermoregulation.
