Foamposite laces?

[aphexacid]

I hate to ask such a lame question, but i seriously can't find the answer by searching.

The tip of one end of my laces on my eggplants finally broke off today, and its irritating the crap out of me. This is the only pair of foams i own and like, and i'd like to replace the lace.

Where do i find an exact replacement? Are these just SB laces? they seem like they are. And i'm guessing i'd need 54"? Size 13

thanks all
