Uncertain about sizing i got both the 4 & the 6...both made me look like a no-asser :( neither fit quite right in the leg. both hit at a weird point in my calf, not cute-short, just off. (i'm 5'8" and 125#) to quote my husband, "nope. not feeling these." that said, they feel great on, seem to be made well, but are heading back to an retailer near you :( sigh. the quest continues :)
