My son wears this Puma for his workouts. He is not a runner though, but he works out about two hours a day. He has this shoe in about five colors and keeps two of them for casual wear because he loves them so much. The grey is very nice looking, he has some of the other colors that we have purchased other places. They are very true to size--he wears a 9.5 D.

It is important to let your workout shoes (actually any shoe) dry out completely for 48 hours. They've actually done studies showing this DOUBLES the life of the shoe.
