Keep trying new brands.  There are goggles made for faces of all sizes and shapes.  Keep experimenting and one of them is bound to work.

i know how you feel... speed sockets by speedo are my favourite for training and racing. speedo is a great brand for all swim gear. try them and let me know they are the bomb

I coach swimmers of all ages and train triathletes.  Most goggles need to be worn the right way.  Be sure that the strap is straight around the back of your head not on your neck. The black foam around the goggles are much better than the plastic too. Do not split straps if you happen to get split straps.  The nose piece can be adjusted on most goggles too. 

The foamless goggles dig in to most people and give a headache especially if you are a novice swimmer and get kicked in the head in a race.

Tighter for races and ocean swims helps too.

Try a little water in your goggles  to keep them from fogging up. Put your head down and youwon't have the water in your eyes and your stroke will be a whole lot more efficient.  That's a 500 dollar tip.  B from swimkids

I train regularly at 2,000 meters, and have found Aqua Sphere (an Italian-made brand) nearly foolproof.  Each end of the strap has a serrated edge, with a ratchet device on the left and right to hold any particular adjustment in place once it is made.  I found them at a local bicycle store that caters to triathletes.  The left and right ratchets make them superior to other brands that have only the serrated strap edge.  I must wear contact lenses (soft in one eye, hard in the other to correct a corneal deformity), and have experienced no trouble with these goggles so far in four competitions.

TYR Rocket Sockets  are the ONLY ones I have found that don't leak in the pool (and bonus-don't leave a huge ring around your eyes) strangely enough, they are also one of the cheapest to buy- make sure you get the mirrored ones if you're swimming outdoors or else you'll be blind! I have tried EVERY brand of goggle out there (I have a full box!) and it actually seems like the ones with the least "padding" are the best for not leaking. Open water (ocean) I would probably want a bigger field of vision so something like a Seal Mask is really good. Thats never leaked for me in all the races I have done in open water. You can order them online for like $9.

I just started swimming about 3 months ago to train for a triathlon and tried several goggles. The ones that absolutely DO NOT leak are the speedo air seal.  I purchased them at Copeland's Sport for around $22. They are comfortable and I can do my entire workout and open water swims without having to adjust them at all.

I agree with the swedish goggles.  I have been swimming competitively since I was 8 years old and am now 32 and swear by those.  I also like the versatility that the different colors provide for indoor and outdoor swimming.  The price makes it extremely convenient to own several pairs.  You can find them at Keifers.com.  Usually under $4 a pair.  You put them together yourself and you adjust everything to fit your face perfectly.  Great in the ocean.  I just swam the San Francisco Bay with no problems whatsoever.
