I have not ridden or tried on the Alphas, but I can tell you that the Transits are very cushy with the air cell footbed. The heel pockets are great too. I took a hard, flat landing from about 5 feet while stiff legged and while it was abrupt, it didn't drive my legs real hard. It is difficult for me to tell you if it's worth an additional $129 bones. I think that has to do with how much disposable income you have and how much more you like the design of the Transit as compared to the Alpha, because I have no personal experience with the Alpha. I do hear a lot of people say they like it. But I really like my Transits, and I have ridden the high end Hyperlites for comparison.
