I would be more concerned about the shoes. The shoes should be wearing evenly. If they have not worn much yet, they should show that they have been contacting the center of the shoe. If the wear pattern shows that the ends and/or sides are contacting but not the center, you need to correct the fit so that the contact starts in the middle and as they wear the contact point grows toward the outside.
If that is the case, let me know, and I'll help you understand how to correct it.
