Shoes for girl and boy (Near San jose mineta airport)

Hi everyone there’s a woman I know who unfortunately doesn’t have much of her life together very well and her two children don’t have any shoes so they are constantly barefoot. I am hoping to see if anyone has size 2 in big kids for the girl shoes or size 5 for a 3yo toddler for the boys shoes because it really does break my heart watching them not have basic necessities. I cannot afford at the moment to buy any brand new so just wanted to see if anyone has some shoes that have been outgrown! Thanks!
