I'm not sure if someone replied to my question but I'll post again.
I have nike TR about a year now. I use the shoe mainly for the gym. No running outside (Might change in summer) just your basic cardio for now.
Should I stick with the Nike free line? Or is there something better for my needs? I'm not a marathon runner by any means. Just to hit the gym. Oh I also wear it to walk to work but I walk underground so no ashphalt.
