The only complaint about Union bindings are the new toe strap they're using. The ratchets are fine....
I personally love my 2010 Union Force. The toe caps fit my boot just fine...... They aren't like some of the other toe cap bindings on the market that wrap a long ways over your toes and a long ways onto the top of your foot. Basically they have a clip that goes over your toes and then the leather part goes over your toes.
But ya, Union Force are the most indestructible bindings that I personally know of.
Thats good to hear. They're on my list of bindings I'm looking at for my Machete (along with Flux Super Titan and Rome Targas).
