I'm about to finish my second pair inspired by that show, which is also what got me to try knitting.
Both pairs are Red Heart Super Saver Multi and H hook. Being male they're not something I would wear other than as slippers.
The second pair was a little lighter and softer so I tried the finished one in shoes. I don't think anyone would wear them as socks without a much smaller and softer yarn.
As slippers go they're holding up much better than a pair of slippers I made out of Bernat Softee Chunky where the holes started stretching out after the first wearing.
The first pair has some fit problems, possibly related to the larger yarn and hook but also related to the less stretchiness of crochet. On the second pair I descreased one midway down the calf, one 5 rows from the heel flap and made the flap 1/2" shorter. I decreased twice as fast as they recommend after the heel turn (on the first pair I decreased about 50% faster than recommended or the gusset would've went all the way to the toe).
The first sock from the second pair fits like a ... sock.
