Do you think a giant snake could swallow me down to my ankles?

I figure it couldn't get over my feet cause they're vertical and all compared to my legs...I'm a 5'9 165 pound guy...Is that at all possible?

If a snake was big enough to swallow you to your knees, it's not going to be bothered by you feet (even if you forgot to change your socks). You would be dead, and your ankles would be limp and relaxed. If this is a fear, I would suggest that you walk around in snow skis. That would probably keep your feet safe.
Good Luck!!

I think it's possible and he would probably just break your feet. That's terrible to think about.

if it very big yeah

yep
obviously it would have to be a very big snake that can swallow very big animals
so probably one of the bigger annacondas could do it
maybe even a few other species
there have been people that have been eaten by snakes and then found inside them
just thought id add that in

LOL @ bimjob

First of all there is not a snake big enough to eat a full grown human, secondly a snake would look at you, size you up and see that it couldn't get past your shoulders, and there have only been 8(more or less) confirmed cases of people getting killed by snakes in the past 20 years or so and over half were children. In all of these cases none of the snakes tried to eat them so lets just sum it up and say that your not going to get eaten by a snake!!!
