Brooks has replaced the Beast so you can no longer find it
at large retail stores. I got my latest pair through Amazon
but, even there, it seemed there was limited availability.
If you are completely "wedded" to this shoe, I'd suggest
buying a few pair now.

As was pointed out to me, the store that advised the Beast was going away was in error
and here is a response from Brooks that seems to explain the confusion. The version I
was buying has indeed been replaced...but by another model of the Beast. Here's the official
word from Brooks:

Hi Kevin,
The Beast has just gone through an update and is under no threat at all to be discontinued. Your store may have been referring to the model that is currently being phased out, the Beast 2010, which has been available for the past 2 years. The new Beast can be found at the following link:

[...]%2012
