I was like you, loving the ZF1's when I first got them. Perfect fit and everything.
Then they packed out, and heel lift, and all sorts of sloppiness started happening.
Now I replaced them with Burton Imperials. Nikes are good initially, but the love gets lost after a while.
Also, after going with speed zone laces I'm never going back to standard laces. Soooo much faster getting from the parking lot to the chair lift... don't know why i took so long to switch over.
Glad you enjoy the Nike's though.
