The Brooks Addiction is similar to the Beast in that it is wide, deep and very stable which is good for heavy pronators. Recently the Addiction 8 was released and it is a significantly different shoe than the Addiction 7.
Toebox Length and Depth – Substantially longer toebox in the Addiction 8 vs. the 7. This may be good or bad depending on whether your heel to ball or heel to toe measurement is longer https://drshoe.wordpress.com/2007/12/05/size-matters-heel-to-ball-vs-heel-to-toe/ The toebox depth in the Addiction 7 is much deeper than in the 8, or put differently, the 7 has more overall volume than the 8.
Width and Outsole Shape – The Addiction 8 is much narrower and has a much straighter last than the Addiction 7. If you have been successfully wearing the 7 you may need to go wider in the 8.
Overall, I’m pleased with the changes and much prefer version 8. It is more streamlined and proportional to the average foot than then 7. If however you have short toes, then you may want to try the Brooks Dyad, which has a shorter toebox than the newer Addiction 8.
