Learn Hardcore Spanish (Latin America): Me pongo una sudadera ligera y mis tenis blancos para caminar. - I put on a light sweatshirt and my white sneakers to walk.

Ponerse is a reflexive verb meaning “to put [something] on oneself.” The me shows the action affects the subject.
Poner without the reflexive means “to put/place” something somewhere: Pongo los tenis en la puerta = “I put the sneakers by the door.”

Can I say Yo me pongo?

Yes, but Spanish usually drops subject pronouns unless you want emphasis or contrast. Me pongo… is the natural default.
Use Yo me pongo if you’re stressing “I (as opposed to someone else) put on…”

What’s the difference between me pongo, me estoy poniendo, and me voy a poner?

Me pongo = simple present: habitual routines or immediate action in narratives (“I put on / I’m putting on”).
Me estoy poniendo = right now, in progress (“I’m putting on”).
Me voy a poner = near future (“I’m going to put on”).

Could I use llevo, traigo, or uso instead of me pongo?

Me pongo = the action of putting something on.
Llevo = I’m wearing (state): Llevo una sudadera ligera.
In Mexico, traigo often means “I’m wearing/I have on”: Traigo mis tenis blancos.
Uso can mean “I wear” in a general/habitual sense, more common with accessories: Uso lentes.

Why una sudadera but mis tenis? Could it be unos tenis blancos?

Una sudadera = an indefinite item (any light sweatshirt).
Mis tenis points to a specific pair you own.
Unos tenis blancos would mean “some white sneakers,” not necessarily your own.

Is los tenis more natural than mis tenis here?

With clothing that obviously belongs to the wearer, Spanish often uses the definite article: Me pongo los tenis.
Mis tenis is also fine; it just foregrounds ownership a bit more.

Is tenis singular or plural? Why tenis blancos and not tenis blanco?

In much of Latin America, tenis is used mostly in the plural for the pair: los tenis.
The adjective agrees in number: tenis blancos.
Singular exists and is heard informally in some places: un tenis blanco (one shoe). In other regions you might say una zapatilla blanca for a single sneaker.

Is the adjective order in sudadera ligera correct? Could I say ligera sudadera?

Why para caminar and not por caminar?

Para + infinitive expresses purpose: “in order to walk.”
Por would indicate cause/reason or movement through a place, not intended purpose.

Could I say a caminar instead of para caminar?

In this structure, para caminar is the natural way to express purpose.
A caminar appears after certain verbs (e.g., salir a caminar) or as an exhortation (“Let’s go walk!”), but not typically after me pongo.

Does para caminar apply to both the sweatshirt and the sneakers?

Yes. In Me pongo A y B para C, the para phrase states the purpose for both items.

It’s acceptable. Me marks the reflexive action, and mis marks possession.

Replace the clothing with direct object pronouns and keep the reflexive:
