Good idea, I was thinking of trying that. Right now I'm using Dr. Scholl's gel heel liners because the heel cup stretches pretty fast for me. Also, I'm wondering about arch support, I think I tend to curl my toes in to point b/c I have too much room in my arch still. Oh how I wish my feet weren't so odd! Oh and I'm most likely going to buy another pair of RR shoes this week, once I decide if I should go down half a size or not, if that would help them fit a little bit better. Right now my toes are at the edge of the shoe, but when I try to drag them, there's way too much of the sole dragging off the end of the shoe too.
