Hi Mark, it sounds likely that you have a Radical ST binding. If it is all black and gray, you have a Radical ST, if there is some green and bronze color to it, you have a Radical ST 2.0. We currently have both in stock, and you can select the one you need from the drop down menu above. I'm sorry to hear that you've broken several of these. It seems that if there is going to be a failure of the Radical ST binding, that the heel piece is the weakest link. That being said, we have many customers who have ...

Hi Bill, the Alien has a tried and true history as a ski mountaineering boot and is definitely up to the use you are proposing for it. The original intent, however, is as a skimo race boot which means that many of the features have in turn been trimmed to a minimum.

Hi Anthony, it's a bummer to hear that you are struggling with the fit of your boots. I've fit the Powertrack 10 on a number of customers, and tried it on for my own fit. I think it will be too tight of a fit in the toes for your Alien RS. The 7mm Ultralight Performance liner will likely be too thin. I have experimented a little bit with the Intuition Pro Tour MV liner in the Alien RS and have found that it could be a workable solution if a person is dealing with too much volume in the calf and heel. You...
