true fit, length wise, but large over the width of the foot with no way to adjust, unless I stitch in a filter insert. They dry really quickly and are well attached, so in all I am delighted, because they are a third of the price of Merrill for comparable quality. I have not tried to swim while wearing them, and then maybe I really won't appreciate that extra space, but for walking into the lake, just to stand there, they're perfect.
as,describ. light weight. also good sole.fits perfectly too.
