Ex Input:

Ex Output:
3

Ex Input:
Bought these shoes 5 months ago and the sole is separating from the shoe already. Things just don't last like they used to. These are the second pair of New Balance to do this! The original look of the shoe was very nice!

Ex Input:
Nice reusable cover, but difficult to fit around the heal of his cast due to the large diameter of the cast. Would love to have the choice of a regular size, or extra large.
