So you’re back from E1. You probably (like me) have a hallway or spare room full of kit. Don’t leave off sorting your boots out! Get them cleaned and polished/dubbined ASAP, and they’ll stay in best condition for E2 and keep your feet happy. I’ve put this off before and regretted it.
I now hand over to Mr Larphacks and his accumulated repository of military-grade boot knowledge.
