They make wide shoes.  The Keen womens shoes tend to be a bit narrow (for me) in the heel area, but these (kids version) are perfect.  Wide through the toes, and just right through the heel area.  These seem to be well made, and have kept my feet dry and warm through an incredibly wet spring here in Wisconsin. We've been on quite a few hikes already, and these are also fairly lightweight.  Perfect with a thick pair of wool socks. Thanks, Keen!
