The Hi-Toe theory is that it moves the centre of gravity higher for lower launch and more spin. So the higher lofted wedges (56˚-64˚) have what TaylorMade called 'full-face scoring lines'. It basically means that the grooves cover the entire face. This is to help get better contact when playing out of the thick rough.
Should I get a high toe wedge?
Overall, I think the TaylorMade Hi-Toe Raw is an impressive wedge. It's got a unique look, excellent feel, and the performance is strong across the board. If you find the right sole design for your swing, you'll have a valuable short game tool.
