Also i would check out slaughson swapmeet and the del amo indoor mall (not to be confused with the del amo fashion center)
both are in not-the-best neighborhoods so just go in there and mind your buiness but they always have shoes that have released years ago, for retail. just walk around and check out the little shoe shops.
since youre close to santa monica, you should go to the pier, i love that place and there is alsoo an umami burger there. if youre down to hit up a secret sushi gem, check out nabeeya on 8th and santee in the fashion district. but make sure you call your order in as there are only 8 places to sit, literally.

Also dont now when your coming, but try to stay off freeway/streets M-F 7am-8:30am and 3:30pm-6pm , Weekends 11am is probably the worst time to be on the freeway . trust me about the traffic, people think im exaggerating until they come down here and get stuck taking 2 hours to drive 30 miles.
