I got to see the new Brooks Pure Project line last night. Since I am completely average and fit in sample sizes, I even got to try them on!
The short and long of it is that all four shoes in the line have a 4 mm drop from heel to toe. They all have that split toe in the front (This is only on the out sole. You do not need iniji socks). They all also have this support, pod like, thing on the sole.
My favorite was the Grit, the trail shoe.
