What shoes are better to wear to the job fair? Are casual shoes ok?

It is best to wear black leather shoes and black (gray) socks, but it also depends on your usual overall style. If you feel more comfortable wearing casual clothes, you can also wear casual shoes, but the color should be clean and solid, and the overall collocation of clothes and shoes should be considered.

In addition, consider the position you are applying for. If you need a suit and tie, you must wear a suit and leather shoes. If it is a leisure service industry, there is no need to be so formal.

In short, even if you wear casual clothes, you should leave a mature, stable, capable and natural impression, so that you can play.

Good luck.
