comfortable shoes

i need more comfortable shoes. for walking. in case the bus does not stop. have i mentioned that i am terrified of buses? i am afraid they will not show. i am afraid they will not stop. i am afraid that i will be on the wrong bus and i will end up in the wrong place and then i will have to get off the bus and i will not be able to get back home. i'll be stuck in the middle of nowhere, not sure where i am, not sure how to get back out. and then my choice will be either stay there and wait for another bus that either won't show or won't stop or start walking and hope i do not get attacked by one of those extra torturey serial killers. and that is why i need more comfortable shoes. and also why it is a good thing that san francisco is only 7 miles across.
