flip turns = goggles leaking

You prob do not realize it but I bet you are making faces when you do a flip turn.

 I have the vanquishers as well and if I giggle while I swim they leak as well.

kind of OT... but you giggle when you swim? hehe that's silly

My mind wanders a lot when i swim and sometimes the pool can be one funny place!  I sure try not to because water in goggles is not funny.

Interesting.   I'll play with them some more.  Thanks!  They might be a bit tight... I can swim 2500 without a leak, but when I'm done my eyes sure show that I've had goggles on.  And they hurt just a little bit.  Maybe they are a tad too tight.

Ouch!  If that's the case, then they're too tight.  If they need to be that tight to keep from leaking, then they don't fit you right.  Try loosening the strap.  If they leak then, try adjusting the nose piece.  If they still leak, then go goggle shopping.

OK, I'll go contrarian here...

First, other than workout inconvenience, does it matter?  **MOST** tris don't require flip turns, so in a race or OWS, not an issue.

Second, in practice, I do the exact same thing...vanquishers or kaimans...with the same result...if I come off the wall hard with my head down (e.g., chin on chest), one edge will invariably leak. If I come off with a moderate push or with my head slightly up, no issues whatsoever.

And I'd warn against cranking the goggles down further as a remedy. That's like taking an ill-fitting corset and making it tighter. Not gonna work, and will bruise you. Comfortable, light fit should stick tight.

I am not going to comment on the flip turns in training in general other than to say I do them and it improves my swimming in all aspects.  That issues has beenhashed out repeatedly on every tri board, just search for flip turns.

However, if your tri is in a pool, yes, you should be doing flip turns in that race rather than seeing who's where (a certain Frenchman lost a gold medal by doing that recently ).  I can guarantee that it's a faster way to swim in a pool

As for the goggles, unless I have a bad pair, mine do not leak on flip turns.

ETA - sometimes it's good to swim with leaky goggles.  never know what is going to happen in a race, including leaky goggles.  Getting used to the feeling is probably beneficial

I agree with everything Chris said but I will go a little further with one statement.  If your tri is in a pool, you should be doing *good* flip turns as it is definitely a faster way to swim in a pool.  My personal experience tells me that a *good* flip turn is worth at least a body length vs an open turn.  So if I can gain 6 feet at every turn in a 25m pool, over a 750m sprint swim, that's more than a 50m difference by the end of it.  Now, all that being said, I swim with some people who do *bad* flip turns at every wall and I am pretty sure I could do an open turn faster than what they are doing. 

Back to the topic of leaking goggles, mine rarely leak and if they do, it's no more than a tiny amount in the bottom.  As Chris said, it's probably good to get used to that feeling, if you get used to it then it's no big deal.   Someone else suggested that too tight might also be the problem and I would agree with that as well.  Mine aren't tight on my head at all, they just fit my face nicely.
