TubeFlops, or what may otherwise be described as the most offensive shoe to ever enter my line of vision.
TubeFlops are, as the name might imply [if you're the type who appreciates cutesy contractions like Brangelina and Cockapoo], part tube sock, part flip flop. And they are awful. The only possible explanation for their purchase is if you are dying for a pedicure in a cold-weather climate. To which I'd suggest you skip the foot grooming before stepping into these monstrosities.
