Shoes and packing are always a sticky point for me as they take up a lot of room. We are planning on being in Austria (Vienna, Salzburg, Hallstatt) in the first half of September 2017. The Netherlands are on the trip too. I will definitely take sandals and running type shoes (for walking).
I am wondering if one can get away with just running type shoes. I have some that I've warn in Italy and go alright with travel slacks. But these would get wet in a real downpour -- not so bad on a warm day with rains but cool days could be a problem. It seems about 60% of the time there are cool days in Vienna in September according to this excellent weather site: weather averages in Vienna
I could also bring hiking type shoes as well with goretex insulation. These would be too warm in climates like Italy but in Austria would they be a necessary addition in September? I'm leaning towards taking these.
Any observations or best practices?
