what is the highest/lowest price for something?"

[tufguy]

Can we ask the following "what is the highest/lowest price for something?"

A customer to a sales person: what is the highest price for the shoes of this brand?

Sales person : $2000.

Customer: what is the lowest price for the shoes of this brand?

Sales person: The cheapest pair can be brought for $300.

I think we can also ask "what is the price range for these shoes". Am I correct?

Try:
How much are the most expensive/least expensive/cheapest pair of Cobblerino shoes in this store?
or
What's the price of the most expensive/least expensive/cheapest pair of Cobblerino shoes in this store?

As a follow-up question, try:
How much are the cheapest/the most expensive?

Sales person: The cheapest pair can be brought for $300.

That's possible, but a more natural response would, e.g., be:
The cheapest pair are $300.

I think we can also ask "what is the price range for these shoes?". Am I correct?

That's possible, but you're more likely to specify the brand or type in such a question.

'What' must be capitalised every time in this post as it's the first word of a quoted question.
