I don't have firsthand experience with this shoe, but arch blisters are easy to prevent... usually. Typically, arch blisters are caused by either a seam on the inside of the shoe just above the insole or by the edge of the insole pinching the arch against the inside of the shoe.
The solution is to prevent the arch rubbing against the seam or to provide a barrier between the edge of in the insole and the side of the shoe at the blister location.
The easiest way to do this is to take a piece of craft's felt about 1 1/2" x 2" and stick it under the insole so it extends past the edge of the insole and up the inside of the shoe in the blister area. Once you've eliminated the problem, you can duct tape the felt in place so it won't move around as you run.
Alternately, you can duct tape over the offending seam (on the inside of the shoe, of course).
Alternately, if it is in fact a problem caused by a seam, you can cut the seam out using a utility knife. The shoe isn't going to come apart if you just remove an inch or so of the seam.
I've done all of these approaches, but usually the first one is sufficient.
