Just bought myself a pair of grey/palm/clay KSO's today. Well, technically, 2 pairs. I wasn't sure which size to get (W40's tend to be comfortable but too small to wear with socks, but my only experience with a W41 in KSO's is my beloved black pair and I know they run small), so I got the two that are in my size range so I can compare them and return the ones that are less comfortable.
Now watch me fall in love with both and want to keep both sizes (one to wear with socks and one to go barefoot in), like I have with my black KSO's.
That makes 9 pairs now (assuming I keep only keep one pair of these new ones, of course). I have the KSO's in all but one of the colors offered for women now and that's only because I don't like the agate camo ones.
