I'm 111.5 lbs and 5'1.5" and typically wear an XS or S in pants. A 29" or 30" inseam usually works OK for my frame but these come down just to the floor.  They might work for excercising in thick-heeled shoes but I bought them to wear for yoga.  There's no way I'd use these for that purpose or for running for that matter.  In addition the cut does not work for my petite frame.  These fall at the natural waistline even though the picture shows the band falling below the navel. They completely cover my stomach and hips.  The pants are also oddly too big in the crotch unless I really hoist them up over my natural waist--in which case they gape at the top. It's a shame the fit doesn't work for my body because the material is comfortable.  The seams and even the tag in the back don't irritate me.  I'd probably be perfectly happy with them if I wasn't petite.
