Well damn. I guess I should've looked around before I posted. I just made a thread about this, saw it this morning on twitter and had a good laugh watching CFB Final.
Pretty much anywhere that sells a good bit of LSU memorabilia, if all else fails you can look on line at LSU sites, or crocs.com.
The only problem with mine is the fuckin toonce on'em, but I haven't found anything to replace them with yet. I mainly wear when I take the dog out, fishing, or just going someplace like the store.
