I'm in the same boat as you! But mine aren't completely destroyed yet. After this season I'm sure I'll definitely be buying a pair. I've been doing my homework on these and I'm pretty sure about Metalheads but also considering the Redsides. Just a tossup between the Boa laces or standard.

From what I've seen and heard from friends with them that they kick butt. The soles cover the entire bottom and the locking system works wonderfully. They definitely stay on better than the old system from the looks of things. I almost broke down and bought a pair a few months ago, but found a studded felt replacement sole for 5$ and that will last one more season.
