Question about boots

[iromano]

Hi:

I've been looking boots and I have found several but I'm not sure if these are valid. I need your opinion.

I think this one is the best, but I'm not sure if they are too high:



I like these others, I just would have to remove the straps and buckles:



Finally, these would seem to me perfect, but they are not leather but synthetic:



What you think that are the best? Or am I still looking for?

Greetings.

The first ones are the closest to the CRL.

The first boots will be acceptable for the minimum standards. The other two will not work.
