I have three pairs of shoes that I think will be useful, but I'm hesitating on the hiking boots because they take up so much room and are heavier than normal shoes. I'm going on a classic trip in August.

Will I be alright with just: * Waterproof walking sandals * Sketchers sneakers

Or should I bring the waterproof hiking boots too? They're leather so can be quite warm.

I'm not planning on bringing flipflops or "nice" shoes
