With 3 picks she could have gotten 1 red, 1 blue, and 1 purple shoe. On the 4th pick, she has to pick one of the colors she already had. Therefore, it will take 4 draws before she'd be sure she had a pair.

I just read it again -- to see that you must have a matching pair in red or blue.

You'll need 5 picks instead of 4.

Can somebody please clarify this (question is slightly modified)
