About Garmont Radium Ski Mountaineering Boot: My name is Paul Parker. I’m the Garmount Ski Book product manager. I would like to show you our Radium Ski Mountaineering Boot. The Radium is a very stiff yet light-weight, high-performance ski mountaineering boot. Based on a one piece overlap. It’s a true overlap that’s high so that it ties the cuff into the rest of the boot. 130 flex index yet it walks better than any tongue design in the market.
