Anybody Know How To Shrink Feet?

Man o man I gotta have some of these:

There are no pictures of these yet on the Brown Shoes website, but the press release tells us of "athletics, casual shoes, sport sandals, beach and EVA sandals, seasonal boots and slippers featuring popular characters from Marvel’s upcoming movie pipeline."

Sadly, this footwear will only be available in "toddler, youth and young adult sizes," which clearly leaves my sasquatch-sized tootsies outta luck.

So, anybody out there know how to shrink feet?? 'Cause I gots to have me some Thor boots...
