Tsarina's tshark shocks resemble sharks that are gnawing off the wearer's feet. They come with knit, velcro-attachable remoras! The comments are full of people begging to buy a pair of these, but there's no indication at this point that they are for sale, either as patterns or finished articles.
The shark theme has been done, of course; this, however, is the Tshark theme…
… and as such it is intended to go farther over the top, and deeper under the bottom, than your average sea-going pedator. (Check out my shiny new neologism that I just this minute made up! "Pedator" – a predator that is worn on the foot, geddit?)
