As mentioned it may just be too small.
I'm with you Matt though, it goes against logic but here's a simple trick to relieve pressure points. I'm only talking a small area or two. Remove the padded lining, not the foam shell.
Swipe a metal table spoon from the kitchen, heat it with a small torch, place the spoon in the area of the foam and you can smooth it like butter. Go slow at first until you get the hang of it.
