You could look at the TheMomEdit blog for some inspiration. The blog now has a few contributors of different heights/sizes/styles so it's interesting to see how different people style things and I've seen them all in longer boots.
Having said that, I have similar boots which I never wear. I don't really like the 70s vibe on me - although I love it on others, sadly long skirts do nothing for me. However I wear mine, they just make me feel too mumsy (I'm in denial - of course, I am probably very mumsy anyway!). So I'd take a look at Pinterest and some blogs but unless you're likely to try any of the looks in real life, I'd suggest you resell them and buy something you love instead. Sorry it's a bit Konmari but if you don't love them, move them on and make space for shoes you love and will wear all the time!
