I'm wondering what the walking surfaces are like on the Portuguese Camino from Porto to Santiago. In particular, I'd like to know if it's as rocky as the Camino Frances. I'm planning on walking the Portuguese Way this coming fall (October 2017), and I'm starting to think about footwear. I wore Keen boots on the Frances in 2015. I would prefer a shoe with more give in the toe box, but I'm afraid that lighter shoes wouldn't be as comfortable or practical if the way is as rocky as the Frances was.
