Really love Lock laces! I bought these for my father's shoes as he is getting old and had a hard time putting on his shoes and trying to tie them on, especially after he got sick recently. Now he can just stick his foot into his shoe, tamp his foot down to get the shoe on properly then do the same for the other foot. His shoes stay on securely all day and he can take them off just as easily. Highly recommend this product. I use these on all my work (I'm a nurse) and walking shoes too with no problems.
