Sabrina the Teenage Witch - The Movie (TV) (1996)

Sabrina thinks she's just an average teenager with average friends and an average school, but things quickly change when she discovers she is a witch with magical powers. She can change her clothes with a few simple words and make her high heels add 30ft onto her height. She can change her friends test scores and make the answers right.

When she tries to cast a love spell on Seth, the cutest boy in school, she soon finds out that witches can't interfere with the human heart, as her aunt Zelda tells her "Love is too precious for anyone to tamper with." Sabrina quickly comes up with a plan. She isn't going to cast a love spell, but she is going to use magic to influence Seth by casting a spell on her running shoes and joining the track team. Sabrina's aunts listen to her plan and tell her that what she is going to do is still wrong, and that if Seth does ask her out after the track meet, and he does kiss her, and true love isn't in his heart, she will be changed into a witch's familiar for 100 years. Sabrina is certain that Seth does love her with a pure heart, so she keeps the spell placed upon her running shoes. However, when she gets to the track meet she has second thoughts and decides to win him on her own. (from wikipedia).
