These shoes are lightweight, stylish, and perfect for road racing and speed workouts.  These shoes are not the minimalist-type, but not the type that adds 1 inch of sole under your feet either.  Since these are very lean and lightweight shoes I am a bit worried about their durability, but I am not concerned because I'm saving these for "speedy" occasions and not for regular high mileage training runs.  Mizuno shoes always seem to accommodate my feet well and fit without causing pain or irritation, and this pair was no exception.  However I believe no shoes can be made for everyone, and I strongly encourage trying them on in a store before buying them or be mindful that there is a chance that you may end up returning them if they don't fit well.
