The one directly to the left of ANH is the senior boot with the smooth sole.
I also prefer the HT boots but those are great alternatives and higher quality materials. The only caveat is they’re hollow so you need to insert your own 1/6 feet.
It’s a very similar promo to the Artisan Anakin figure. Similar base too. I wonder if this was intended to be an Artisan figure earlier in the development.
The feet are definitely not small. They’re bigger than the ANH feet. There are short DiD boots but they also offer tall ones. I have two different models of the tall DiD boots. Here’s a quick comparison.
