PDF fins

Anyone use these Positive Drive Fins from Finis? Curious to hear about sizing the closed toe and if they run true to size. i'm a men's size 8 and bought finis L size, M 6.5-8 positive drive fins www.finisinc.com/.../positive-drive-fin.html], and they were too tight. i also have finis E size, M 7.5-8.5 Z2s www.finisinc.com/z2-gold-zoomers.html] (which are open toe) and they're just right. (also the Z2s are less stiff than the positive drive fins, which is a plus for me.) i wear 8.5 sneakers, so maybe sneaker size is the way to go.
