Yes, it is necessary. This is a substantive subordinate sentence, and they are always introduced by a linker or an infinitive. The linker is usually a conjunction (que, si) or an interrogative particle like qué, quién, cuándo, cómo, dónde...
You can say "yo pienso", but I would say that in this context "creo" fits better. "Pensó" is past tense for the 3rd person singular (él pensó).
AND, "I believe these shoes are small" is a typical way of saying it in Florida (USA).
Why is "Me creo que estos zapatos son pequeños" Incorrect?
I get so confused with Mi, me, mis and yo.
It is a little confusing. When in doubt, use Yo. The exceptions, where you'd use Me instead, are less common. Here's a list of some of them: Me despierto = I wake up Me levanto = I get up Me ducho = I shower Me llamo = My name is / I am called Me gusta = I like Me puedo = I can / I may
Mi and Mis are possessive. Mi = My (singular) & Mis = My (plural). However Mi is also used where you'd use the English "Me".
The shirt is for me. La camisa es para mi. Will you walk with me? ¿Caminaras conmigo? (Notice the Mi is inside 'conmigo')
I was correct to choose "que", but still don't know why "ese" would have been wrong. How can you tell which one to use for "that"?
It is wrong becuase "zapatos" is plural. The plural of "ese" is "esos". In my first comment I put how this word (este) changes with gender and number.
I gather then that "ese" would be used for "that" as long as the subject is singluar while "que" is plural. If I'm still wrong, please let me know. Many thanks, have a lingot!
There is no relationship between the "que" and the "esos". There are two different parts here:
- Yo creo que... = I think that...
- ...esos zapatos son pequeños = ...these shoes are small.
The second part is the one that can change with the number and gender of the subject in the subordinate sentence:
- Yo creo que este zapato es pequeño.
- Yo creo que esta casa es pequeña.
- Yo creo que estos zapatos son pequeños.
- Yo creo que estas casas son pequeñas.
