I am planning a trip to Scotland next May and going with Scottish Tours and their Highland Highlights. I am planning to bring light colored walking shoes...very comfortable, but being so light, I am afraid that if there are muddy places....I will find them....and although this wouldn't normally bother me....after Scotland I am heading to Paris....and really don't want to walk Paris in horribly soiled shoes...no matter how comfortable. I am traveling with only carry-on luggage, so I don't have much room to work with. I have seen a pair of foldable boots to cover my shoes, but I don't know if I will really need them. I can treat the shoes to repel stains, but that only works kind of...sort of...halfway well. And buying something while in Scotland is an option, but probably pretty expensive for just a week. The Highland Highlights tour goes on several day trips from Inverness to places like Isle of Skye, Stirling Castle, Glencoe, Cairngorm Natl, Park, John O'Groats, Loch Ness, Applecross, etc. Thanks for any words of wisdom you can share as they will be greatly appreciated.
