Do something like
select (t).* from (select get_desc_and_price(shoe) as t from ...) ss;
If you don't have get_desc_and_price marked as volatile, you'll probably
also need to add "offset 0" to the sub-select to keep the planner from
flattening the sub-select and producing multiple calls of the function.
