Question: During jury selection, Kevin decides to have one of the jury dismissed, I believe, because of the shoes the jury member wore. What exactly do the guy's shoes have to do with anything?
Question: At the end of the movie, how did Kevin's decision to not represent Getty's make him lose his case and how could he possibly be disbarred for making such a decision?
Answer: In short, a lawyer may not withdraw from a case if doing so will adversely affect the interest of client. At this point in the trial, if he withdrew, it could prejudice Getty in the eyes of the jury (i.e. they might think he's guilty because his lawyer doesn't want to defend him anymore). Source: Florida RPC 4-1.16 Declining or Terminating Representation.
But, could his refusal to represent Getty any longer allow Getty to get him disbarred?
The State Bar Association would be the entity that would determine if Kevin will be disbarred. All Getty could do is bring grievances to the Association, but it would be a matter of public record that Kevin withdrew in the middle of trial that and it would be more likely that the Judge reports Kevin to the Bar. Getty's recourse of action would be to sue Kevin, but that wouldn't result in disbarment.
Answer: The shoes showed him this man polishes them every day, also his clothes are custom made. That all means the look he has of a black thug is deceiving, instead he's a cautious, proud person they can't use in the jury. Just to add, Kevin knows all this because the devil (his father, spoiler alert) is giving him the talent to do it, not a logical explanation can be given why he dismisses these people.
