If the user is searching for a shoe make, he might want to bookmark
one of the results so he can come back to it later (perhaps he's
comparison shopping with other sites).

You do need to worry about bookmarking such pages, especially if
you're selling something. If the user can't come back to the page,
you may lose a sale. Now, some things shouldn't be bookmarked (like
a customer's list of what's currently in his shopping basket, or a
partially-completed order, or a map to the store based on the
customer's location), but pages for individual items for sale should
be bookmarkable.
"dynamic pages" are usually an implementation detail. If the
contents of the page depends on things like the item number, search
terms, category, etc. and not on the customer's ID number, customer's
password, or customer's geographic location, chances are it should
be bookmarkable.
