I'm going on this trip in February 2018. I plan to bring shearling-lined boots for snow. I noted the Tauck recommendation for walking shoes with ankle protection, which essentially means bringing my hiking boots. As both pairs of boots are very bulky and I don't like wearing them on planes, I would like to do without the hiking boots in favor of a comfortable pair of hiking/walking shoes (which I will wear on the plane). Is there any reason that this trip will be especially hard on ankles thus requiring that I ditch the shoes and bring hiking boots? Also, can I assume Tauck's recommendation for "casual elegant" clothing for dinners does not apply on this trip?
