Water in goggles

Not more expensive goggles but different fitting ones.  I had some Aquasphere Kaimans that alot of people liked but they always seemed to let water in.  I switched to a cheaper pair of speedo goggles that are smaller and they keep all water out for me.

I tried a couple of different pairs but found that the speedos fit my face the best.  Plus they have large interchangable nose bridges to span my shnoz.  The different brands have different shapes and fits.  Once I found one that fit, I've bought a couple different models and had no problems.

Good Luck!

I agree with dalessit.  It is just a matter of finding the right fitting goggles.  For me the Aquashere Kaimans, were the magically ones after trying several others.  Goggles definitely are not a "one size fits all" product. 

It's not so much the expense/quality as whether they're a good match for the shape of your face. You may need to try different types to see which fit you the best.  Heres' a fit test  - Press the eye cups into your eye sockets, lean forward with face looking down at the floor and let go - they should stay in place for at least a few seconds if they are a good fit. 

Assuming that you have the right goggles for your shape face, then over tightening the straps may cause the seal to be lost, allowing small amounts of water to leak in.
