I know this is an old thread, but I'll opine on I anyways.
With interesting objects as still lifes, think about why you think they're interesting, then convey that in your photo. It usually involves adding context to the object. Shoot the boots at an unfinishd work site, in an old shop, in an entryway to an old home with a leather weding apron hanging above them, etc. You're adding context to the boots, not just cataloging old boots.
