once again, the pattern is in the right hand column, in the "patterns" category titled "doll shoes."
out of felt (or pleather or whatever) cut 2 tops, and 2 bottoms. (make sure you have a 'right' bottom and a 'left' bottom)
right top sides together, stitch the heel seam.
right sides together, carefully pin each top to it's sole. you might consider hand basting. I do that with the dolls' feet... all those pins can become cumbersome on such a tiny little surface, and it is important to achieve a nice smooth line of sewing. felt is pretty easy to work with though.
turn right side out. in order to give the shoe some definition, I usually blanket stitch around the bottom seam with either matching, or contrasting embroidery floss. and add little french knot flowers, etc., but since these are for a boy, we'll let them be!
