Judging by his past podcast with mark from lpp (if I recall correctly) along with a few comments on ig it sounds like Sammy breaks boots every few weeks and has been running the gamut of touring/freeride boots just trying to find a boot that will hold up for what he does.
Probably too early to tell, but who really knows. Dudes probably just trying to find a boot that works rather than trying to keep running through boots.
