Hi, there is no other way but: 1. Make sure you have latest version of the theme and woocommerce. 2. Have localization specific woocommere. 3. Anything else you can translate via plugins that can edit theme files. We use woocommerce text-domain in our files so official woocommerce translations will work.
If not, install some better plugin (like wpml for exaxmple) and change the texts yourself.
