I've never found Tony Lama boots near me, so I've never been able to try them on, but I want to buy a pair. How do they fit? Are they like Ariats, or Justins?? True to size? Narrow? I have high insteps and arches, and usually wear a womans 7.5 or 8. Also, how would you compare a pair of Tony Lama boots to Justins or Ariats? Thanks!
