Jonesy, I recommend a pair of grey sandals similar to the black ones you're wearing with the paisley pants. They will go with many spring colors and aren't so light or nude which you feel doesn't work on you.
Angie suggested grey footwear with colored pants way back and she is right, they work really well.
And incidentally I like the way the paisley pants work on you and don't feel the fit is off or that they are unflattering to your hips and thighs. But tapering them at the calf/ankle would have been necessary as well as lighter footwear.
