DS (14) is now size 10.5 so has outgrown Clarks school shoes. We've been looking at their adult shoes and also M&S mens' shoes. We've bought and returned 2 pairs because they had relatively smooth soles which slid (and in one case also squeaked) on our wooden floor at home. They may be ok for adult office wear, but DS needs something he can run around in safely and comfortably. Any recommendations for a particular style that works for active teens?
