I have the tragic misfortune of having extremely flat feet and loving plyometric workouts - ie anything Jillian Michaels or P90x. I recently realized that I should NOT being doing these workouts in my running shoes as it causes unbearable pain in my non resistant arches and shins. Once I realized this, I have been on a crusade to find the right shoes for my poor feet. So far, I've tried the Asics Gel Blur 33, and wasn't overwhelmed by their wonderfulness, and since a lot of reviewers said they did similar workouts in these New Balance shoes, I had high hopes.

I have discovered that these shoes - for people with flat feet - do not provide major pain relief when doing significant cardio (Jillian's kickboxing dvd, blast fat dvd) but will be sufficient for her circuit training DVDs as not a ton of jumping around occurs.

Bottom line: not a dream shoe for the flat footed, but depending on how much plyometric moves are incorporated could be sufficient for a gym workout or circuit training.
