Not all shoe styles with Velcro are suitable for old people. Yet some styles fulfill a need. Think: one foot wider than the other; arthritic or old fingers that make tying laces and manipulating buckles difficult.
As people age, feet can widen and/or develop bunions, hammer toes or other problems that cause one foot to fit better in another size--or width--shoe. This is where Velcro comes to the rescue.
