Hi
@Mamama13 I used Arroyo IIs as my primary footwear a couple of years ago going from St Jean to Finisterre and comfort wise they were perfect from my first step.
The issues I did have were the bungee type laces which weren't terribly durable. I realised after a couple of 100kms of walking pre Camino they probably wouldn't last so I contacted Keen and they sent me a spare set free of charge. I also wasn't delighted about the durability of the uppers where the neoprene lining was pretty worn out by the end of my Camino. Having said that I'm heavy and tend to be pretty hard on my footwear so your experience may differ.
For me it was worth a slightly shorter lifespan for out of the box comfort and a blister free Camino.
Hope this helps.
Rob.
Edit following @shazpisting I can confirm that the holes in the Arroyos are sufficiently small that pebbles weren't an issue.
