I live in Hong Kong and I am going to spend my winter trip in Japan. I bought a long coat which stated at 90% wool. For boots, I am looking at Bodyline SHOES224 which seems it can prevent the snow melt and go inside the boots.
Does the above enough for a Snowy Winter at about -10 to -15°C?
I know this is such a silly question but it is the first time I met Snowy weather. I cannot image how cold it is since the coldest day in Hong Kong is only 7-9°C.
