In need of warm feet? Around base camp after the ascent, in a hut after a long cold day of hiking in heavy boots or after a sunny day of backcountry skiing. The ankle high flexible and soft booty snuggly fits your feet thanks too an elastic heel strap and cuff and should be in your pack at all times. The 0.4 cm EVA inner sole give you the feeling of walking barefoot but offers enough insulation. They let you enjoy the sunset on the veranda of your hut wrapped up in a quilt.
