I really don't know what these guys are talking about above rating these three or four stars. I am a huge dude, maybe you've seen me on the slopes, the only brown guy riding whose 6'4'' 265 lbs. Needless to say I ride hard and do damage to everything I ride or strap into. These bindings are no different and have held up to the test. The convertible strap is rad, I always go over the toe, but what's sick is it gives you almost limitless potential on where to have your toe strap. It's ultra sickness; pull the boot in tight or keep it snug to the board. Bottom line. The SPI's are a Super Pimp Item.
