Is this a specific type of tostada?

I just bought some aguachile from my local Mexican market and they gave me a few tostadas to go with it. They are absolutely AMAZING, my question is what kind of tostadas are these?

They’re really light, airy, and slightly puffed like a crunchier fried rice cracker. Every other tostada I’ve had in the past is very crunchy and denser(think Guerrero yellow bag tostadas). Is this just the market making bomb tostadas or is it something specific I can look for at other markets like a baked tostada?
