Brooks Beast is a tank. Great for those of us with wide, deep feet. Slightly heavy, torsionally stable (no lengthwise twist), with a heel slightly wider than the forefoot.
I must say, however, I was disappointed to see the change in this years model, compared to prior years. Today, someone came in having ankle and ball of the foot pain, which didn’t happen with his prior year Beast models.
Unfortunately, a quick comparision of 2006 vs. 2007 models shows considerable differences between the same brand name shoes. Today’s runner, started feeling the pain, with his new shoes.

Not only is this years model (blue) narrower, it also has a less thick (shock absorptive) outsole and a less deep toe box.

For many people wearing Brooks Beast, the above changes won’t make much of a difference and this shoe will still be fine. If you have ball of the foot pain though or need a deeper shoe, then these design changes may mean the difference between comfort and pain.
Even though a shoe keeps the name, you always want to compare it to the prior model, as design changes may help a shoe company’s bottom line, but not necessarily your foot.
