Hey I just found these ice/ mountaineering boots for sale, and they are a huge bargain (at least by Korean prices). They are Asolo ASF Guida plastic boots, reduced from 640,000won to a mere 270,000won. They are a perfect ice climbing boot, and flexible and comfy enough for snow hiking etc. Look at the web page for the Alps Villa Gear Store in Seoul (Jong-ga 5 area).
