I'm a big man, I go 250 and these shoes have held up great! On top of being heavy I am a major heel stomper so I must have a solid heel as the air pocket heel etc. don't last more than a month with me. These are good solid pair of runners and when mine got worn some I put in a new inner soles and got another year's worth out of them! Great shoes, NB lasts me years longer than Nike or Reebok ever did. I am NB buyer only now.
