With one shoe operational in the better grip for running thing it was time to get the next. Surely grip wouldn't be the only thing saving you in situations but it did help some. Imagine casting but slipping while you do and missing. Missing was the difference between living and dying. This was why she was so happy her aim was that good. Hardly ever missed. This no slipping would increase that.

Alexa stuck out her left foot, feeling some amount of protest in her knees. Merlin, joints that weren't stiff, they helped with running too. Definitely.

"Henshu!" Twist and horizontal flick.

How did her shoes feel now against the floor you may ask. The exact same...as each other, which meant the spell probably worked just fine. Either that of the other one had worn off because of poor casting? PFFFT, she'd go with the first thank you very much.

Lex ran her feet along the ground. She would have opted for a small jog but yeah...knees were saying no and who was she to argue with them?
