I'm hoping for some input on a couple pairs of boots from any of our Pilots and of course Mr. Code

Going off discussions on the JRS forum, both pairs would need to have the bottom strap/buckle removed.
The first is a 13" with a pretty aggressive tread.
Not sure if this is acceptable:

The second is 16", with a more subtle tread:

Both appear to have a wedge cutout above/behind the top strap with elastic in it.
Are either of these a viable option once appropriately modded, or do I continue the hunt? Thanks y'all.
