None so well shod but they may slip.

You can take all the right precautions but the unexpected can take you by surprise. This sounds like an advert for insurance and it is an awareness of unlikely accidents that presumably motivates most people to consider a suitable policy. In the modern world where we rely on our computers this leads us to think of the importance of keeping good backup. Expecting the unexpected constantly could drive a person to a nervous breakdown so common sense is required. The worst rarely happens but some sensible precautions can give peace of mind.
