Should I Clip My Shoes to My Backpack While Traveling?

So, after chatting with some folks about my travel plans, it hit me that I should pack both my sneakers and boots because my trip will be all over the place. And let’s be real, I don’t want to give up precious space in my backpack. I’ve seen people hooking their shoes to the outside of their bags, and it seemed like a smart move. I’m not going on any extreme adventures – just hopping between hostels while interrailing. I doubt I’ll have my shoes hanging for ages, but I’m open to hearing if anyone thinks it’s a terrible idea. I might just bring my old sneakers along, so if it turns out to be a disaster, I can easily ditch them without any regrets. Plus, I’ll be flying a few times, but my bag will go in the overhead compartments, so I’m not too stressed about fitting it under the seat. Oh, by the way, I should clarify that I won’t be hooking the shoes directly to my bag; I’ll use a separate travel bag to attach them.
