Sarah takes her crutches and crutch down on the dock at the marina.
Suddenly one of her crutches slips on the slippery wood but like the pro she is she manages to keep her balance but she decides to take a different route so she doesn't slip and injure her foot again.
She crutches up a ramp before sitting down to put on a black sock over her now old SLC.
You can tell that Sarah has been using her crutches for a long time because everything she does with them looks so natural.
