I like most of the features of my k2 uprises, but the fact that the auto does not release the toe strap caused me to kick the shit out of it over 50 days and plenty of em park laps, basically destroying them. The toe strap is the best toe strap concept around in terms of fit, I would say the engineering is not quite there in terms of bombproofness.
I know plenty of people have a different experience, and I would totally get another pair, just personally would get a conventional 2-strap over the auto.
Otherwise the bindings are plush, canting and dampening are nice, the ankle strap hinge is a no-brainer that everyone else fails hard on, the ratchets are smooth, there is even a funnel for the strap entry - clever.
is it late october yet?
