I am planning to walk the entire Camino in May of 2018. I have watched a number of documentaries on YouTube and the consistent complaint is extremely painful blisters. I understand that I need to break my boots in (need to buy them) well before the trip. My question is - does it make sense to also bring a pair of trail shoes so I can alternate between boots and shoes - hopefully preventing "hot spots" from wearing the same shoes every day? My trail shoes are light and well broken in. Thanks is advance!
