How can i get my characters feet to lie flat? I used Cntrl A along the x axis to widen the feet and attempt to make them look flat.  Yet Cnrtl A (x) widened them along a diagonal.  Can anyone tell me what I did wrong in creating flat feet?  Thank you for any help you can offer.
Select the group of vertices that represent the shoe sole and press Shift+S-->Cursor to Selected.


Scale it along the Z axis (S,Z) and press 0.


Add a loopcut to sharpen the edge. Press Ctrl+R, confirm the cut with Left Mouse Click and place the loopcut at the bottom of the sole.


Here's the result.
