Good advice

When I die, I either want to be cremated and have my ashes somewhere meaningful, or I want to be buried in a suit of armor with a big ass sword and a bow and arrow. That way, I can fuck people up in the Skeleton War!

Also, most people are buried in their best clothes and shoes—high heels, loafers, flats, Oxfords, dress shoes—most of which do not have laces. In fact I have never even heard if someone being buried in shoes with laces at all.

Most zombie apocalypse scenarios are caused by a pathogen infecting the living or recently dead, not the dead and buried. It'd be difficult for the pathogen to get through 6 feet of dirt and into the coffin. (not impossible, but unlikely) And even if it does infect a buried corpse, it's extremely difficult to get out of a coffin and to the surface.
