Slippers for enormous feet

I have a problem. My dh wants some slippers and I wanted to get him some really cool ones BUT he has enormous feet. He wears size 13-14 and larges are 11-12! Wear can I get some cool slippers to fit his giant feet?

DH wears 13 and I get his slippers from Kohls.

Ugg!! They have some of the softest slippers. I love my pair and they last a long time. DH loves them too. He wears a 13 and has wide planks for feet.
