The Stock velcro pad was too thin around my nose and so the goggle frame would dig in.  The Foam stick on sponge pad was comfortable but is already falling apart.  I am not seeing many replacement options other than replacements for what shipped with the goggles.  Is there a company that makes durable super plush replacements?  Or  maybe some DIY options that are more durable?

I’m interested too because the pads with my new 04X are mediocre at best.

I use these ones. Bear in mind that you probably want to cut the nose out of it as that sucker cuts really bad. Outside of that, it's the best foam I've used so far.

Edit: Just noticed that they're sold for a ton of different prices. Shop around!
