I think for most people, "ticklish" = "can't stand tickling." Ergo, someone with very ticklish soles is someone who can't stand having them tickled.
Now, that's not the same as "hating" the sensation, but for a lot of people I think the two go together; browse a sampling of blog entries with regular folk talking about being tickled and you'll find a lot who hate it with what they characterize as white-hot rage. Because they can't stand the sensation, and (probably because of that, but also possibly because of other issues) that makes them angry and/or miserable.
Now, my feet are as ticklish as they can possibly be; ain't no feet on earth more ticklish than mine. And I honestly can't stand having them tickled. It's a quintessentially intolerable sensation. Start tickling them and I'll flail, shriek, protest, beg, and bargain. But (not surprisingly, given where I'm posting) I don't hate it (which is just as well given all the friends and colleagues over the years who've insisted on tickling me ALL THE TIME).
The difference is probably summed up in related remarks I've heard from two different women, each of whom made it a habit to tickle me silly: one of them said her boyfriend was ticklish but he became violently angry the only time she tickled him and demanded that she stop it; clearly she was delighted not only that I was as helplessly ticklish as a defenseless schoolgirl but also that I didn't get angry each of the gazillion times she did it to me. The other woman said something similar about her sister--how her sister was almost (!) as ticklish as I am but that tickling made her furious (and thus, presumably, less fun).
