Razorback, I don't personally own the shoes pictured but here's what I can tell you about CL sizing... I think most ladies' true CL size is 1/2 up from their normal size. Take me for example, I normally wear a size 8(38) in most shoes, but my normal CL size is 8 1/2 (38.5)... as for specific shoes, they all run the gamut so it really just depends on the style... I think if you look above there might be a sticky discussing sizing issues.... Hope this helps!
And if none of this is helpful, maybe you should just buy both pairs and keep the one that fits!
