There are as many opinions about shoes on the forum as there are pilgrims. In the end, it's a matter of personal choice.
I've walked the
Camino Frances twice, the Aragones Route, the Portuguese and portions of the Norte and Via de la Plata.
I've worn only New Balance trail shoes with Motion Control Inserts. New Balance makes a shoe with a very wide toe box, giving your toes a place to spread and not rub together. The soles are flexible, perfect for 6 hour per day walking. The Motion Control inserts not only protect the sole of your foot, and give extra support in the instep, they support your ankles as well by giving your foot control. You can wear these shoes out of the store and directly onto the Camino with no breaking in. That's how well they fit.
In my opinion, unless you have weak ankles, there is no place on the Camino that warrants hiking boots. More often than not, the trek is a gentle one.
The other reason I like New Balance trail shoes is that they easily dry overnight. Boots are often still wet and stiff next morning.
Lastly, the worst blisters I have ever seen on the Camino were sported by people wearing hiking boots. Often, the blisters were on the ankles or toes. That said, I met a Mexican boy walking the Camino in his cowboy boots!
Do a search. You will find long, long threads on here regarding boots vs. shoes. As I said, in the end it is a personal choice that one must make wisely.
