It's not just that Bread Slippers exist, it's that Bread Slippers exist in so many styles of toasty foot loaves! French baguette, country white, marble rye, sesame seed, multi-seed, hot dog bun...my blood sugar is spiking just looking at them all.
If I were getting a gift for a woman though - and, really, they say Bread Slippers are unisex, but unless you're wrapping them up as a gag gift or for your local baker man, the house shoes seem pretty lady-like - I'd go with the French baguette pair. Classic, stylish, and the kind of bread I'd most like to slather some butter and jam and Nutella all over for an unbridled foot...uh, I mean food fest.
All of the Bread Slippers have realistic bread loaf images printed on their tops and sides, and open-backed slippers continue the printing along the foot bed, for nifty glutinous wheat interior effects.
