I got my pair of Lamas today. I tried to photograph them each in the same position and creases as the shot of Danai holding the boots.
I had to shoot each boot individually to them to sit right. I resized them to match then cropped them all down the middle like I did before then mirrored each image so I could mate them up with the same boot from the Danai photo. Here is the result and I think this should remove all doubt that she is holding Lamas.
Then I did the same thing with a screen shot from the episode where she picks them up.
I tried to photograph my Justin and Lama boots from the same angle with the same fold.
Strangely enough, my TLs folded easily the same way the screen boots do but the Justins wouldn't.
They are cut differently. The foot portion at the heel goes up the back an inch higher on the TLs.
I resized my photos so they matched the screen boot then removed all the background, cropped my boots down the middle then lined them up as mirror images with the screen shot. With them side by side you can see the Tony Lama pattern quite clearly where the Justin just doesn't work.
I am satisfied that the boots she picks up in the show are the Tony Lamas too.
If I come across a better picture of the boot full of water I will do the same but I would say that at the very least, the Tony Lamas are the boots Michonne finds in her final episode. Whether they were actually on his feet and on camera is another mystery but the water pour shot would seem to say they were.
I read an article where Womble talks about how destroyed the Justin boots were by the time she left the show after season 6 so maybe someone will get a chance to ask Montalvo about them. There was still a pair of Justins out there as they are sitting on the blanket while they have a picnic in season 9.
