I have the Rincon 1 (similar to the 2). I pronate in all off-the-shelf shoes, moreso on the right foot, so I modify the insert or outsole. I do this on all my running shoes.
I checked the Rincon. It's worse than most of my shoes as far as pronation is concerned. When the pronation is slight, I add crafts felt under the insert on the inside of the heel and in the arch to cant the shoe more to the outside. I've described how to do this many times and it's in my book. You can probably find it with a search here.
However, on some shoes, including the Rincon, this isn't enough so I removed about 1 1/4" of the outsole along the outside of the foot starting just in front of the heel and going up to the base of the little toe. I went down until that area was level with the base of the pads. (Basically, I cut off the pads.) This, plus a layer of crafts felt in the arch, makes the Rincon tolerable.
The crafts felt hack is a great way to get a better fit to prevent injuries caused by pronation.
