I second JustOneGuy : it's impossible to know because each foot is different. Go to a shop if you can.
And as an anecdote, here is my little cautionary tale : I went to a specialized shop, had great advice, tried the Hoka Anacapa 2 (women - low), enjoyed them, bought them in 1and a 1/2 size larger. They were great for small hikes.
The week before my departure, I finally got the chance to try them in a long hike (the temps were over 35°C pretty much all summer before that), and I got a nasty blister on the side. Ah well, they were still lighter and more breathable than my other hiking shoes, I thought stupidly. I'll do my Camino with them.
The first day went ok, though that blister was killing me and each step put an added pressure on it. So I started walking differently in order to avoid that pain. Halfway through the second day, I tore my psoas. There was no false movement, I didn't stumble. It simply came from me trying to avoid the pain of that blister. I had to go back home the next day (thankfully, I had started directly from home, as I live in France).
I looked at the Hoka more closely after that and realized that the heel part inside was quite narrow and went steeply up on the sides. And it just so happens that I walk in a lopsided way (all my shoes get worn a lot faster on the right side of that foot). So that configuration didn't allow my foot to do the movement that came naturally to it in wider shoes.
Anyway, (very) long story short : the anacapa weren't good for me because of the way I walk, and that illustrates how personal shoes are! And also, don't be an idiot like me, always listen to your body : I didn't listen close enough to that blister and ended up with a torn muscle....
I hope you find good shoes and enjoy your Camino!
