Last year I spent the entire season on my Ride MIGs, the alpha is the new evolution of the MIG. The new base trays are lighter weight than last year, new ankle strap is comfy and designed not to cause pressure points. Toe strap is comfy and stretches over your boot so you can put it anywhere on your boot. The high back is nice and responsive, like last year ride is using the Aramid Fiberglass in the high back just like their boards. It is light weight and very responsive like carbon fiber, but you don't have to worry about it chipping or breaking. They can lay it in so many different patterns to create different flexes through the whole line. If you ride all over the mountain and are looking for something versatile that will kill anything you throw at it, these are a great choice.
