I've recently purchased my eight or ninth set of these goggles. I love everything about them except the foam on the frame. I use them when I ride my motorcycle and find myself replacing them every few months.
My guess is the foam is as porous as it is to help with fogging, but the end result is foam crushes in spots and ultimately looses its memory and becomes useless as padding.
If these came with a more sturdy, lasting foam / cushion, I'd probably call them perfect.
Pros: Fit great, flexible, lenses easily replaced
Cons: Frame foam wears out fast, straps can loosen unintentionally
