509s are not true OTG style goggles. Meaning there isnt a notch along each side of the goggle for glasses. That being said we have some of the thickest foam in the biz which provides for more room inside the goggle for your glasses. For example 509s have 33% thicker foam than spys.
So compatibility with glasses depends entirely on the size of your frames. Alot of guys do run 509s with glasses. You are more than welcome to try them and of course we will accept returns if they don't work with your glasses.
So you must have upgraded the foam big time from last seasons version. The ones I got from last year have less foam than any I have tried. That's why i don't wear them much. They look cool but don't seal to the face very good. That said, I still go back to my Scott Voltage X's with blue lens.
