The sock is surrounded by a thick but extremely soft, microsupreme terry material particularly suitable for snowboard boots. This medium weight sock adapts perfectly like a padded lining to every boot in any condition. Medium density padding absorbs shock and eliminates friction. Ventilation channels strategically placed between the padding, transports moisture away from your skin. Superior moisture management by Microsupreme provides warm and dry comfort; an ideal feature for other outdoor activities practiced in difficult climate conditions.
