Size-wise, these fit tts.  I usually wear a 9 in running shoes and I took a 9 in these.  I have average width feet and bought C width, no complaints.

I ordered these and have worked out in them twice since, one day I ran outside on concrete (about 2 miles) and the second day I did strength training and 3 miles on an elliptical machine, and my feet were killing me during and after exercise both times.  The two pairs of shoes that I owned before these were an Asics Gel-Nimbus and pair of Sauconeys that I picked up at Marshalls (grad student, didn't have a choice).  These shoes are a definite downgrade even from the Marshalls purchase, and don't even compare to the Nimbus series, which I owned for an entire year, running 5 times a week.  The balls of my feet were numb during and after both exercise sessions and my feet hurt so much after the run that I was limping. I didn't find the shoes to be breathable either (if that is a selling point for you, I know it is for me).

I think that these shoes might be appropriate for someone who jogs lightly on padded tracks or on dirt tracks, but they are not for the urban runner, or for anyone who exercises with great regularity.

I will be returning these tomorrow, wish me luck with the return process.
