Because every year as lobsters grow they have to shed their shell and grow a new one. The soft shell lobster's are aka "new shell" lobsters, and they haven't had time to toughen up their shell. Hard shell lobsters are aka "old shells" because they shedded a long time ago, and their shell has had almost a year to harden up.

Hermit Crabs are crustaceans like crabs and lobsters, however they have a soft very vulnerable body that is somewhat coiled upo itself. To protect this soft body from predators or any other threat, they use a hard shell. They can also retreat completely into this shell, which also helps predators from being able to pry them out.
