After רוצה (want), Hebrew normally uses the infinitive, just like English uses to + verb.
- רוצה = want
- להחליף = to exchange / to replace
The ל־ at the beginning of להחליף is part of the infinitive form, so the whole phrase רוצה להחליף means want to exchange.
להחליף can mean to replace, to switch, or to exchange, depending on context.
In this sentence, because we are talking about shoes and size, it most naturally means to exchange or to replace with a different pair/size. In a store, אני רוצה להחליף את הנעליים is a very natural thing to say.
