Heel-heavy wear - cobbler or DIY?

Hey y'all,

Cobblers aren't easy (or cheap) to come by nowadays. Apparently I'm a heel-heavy walker and my boots ALWAYS wear out on the heels before anywhere else. Is there an easy way to repair those soles myself or should I bring it in to a cobbler to even out the wooden heel?

I can literally rock back on forth on my heels like a rocking horse.
