Suja, BIIIIG fan of OTK boots here, so be warned. I'm short, too.
I think these fit close enough to the ankle and leg, that they don't appear to cut you off. I really like the look. I don't think you need to limit the look to low-contrast, although certainly low-contrast will help lengthen your overall silhouette.
I'm jealous -- I found a great pair of greige OTK that I am finding I wear a LOT with the cold winter we're having! But the shade of these you are wearing looks yummy!
