I appreciate the answers, but now I'm confused. (wouldn't be the first time..probably won't be the last.) I'm not much of a seamstress, are you saying I should buy the soles a size smaller than what I need? I wanted soles that cover the whole bottom and that have pre punched holes to make sewing them on easier. It would seem to me they would pucker because they are bigger than the bottom of the slipper is. Has anyone put complete leather soles on the bottom of clogs?
