The Nat runner has a fine, neat profile, one might even say 'feminine'. It has a gusseted tongue, so you can wear them without the laces...handy if you're disembarking a long haul flight! The gusset can be carefully cut though, if you want a looser fit.
As with all the Frankie 4 sneakers you have a removable functional footbed that gives you heel support and full cushioning, including arch support. The fit pack that's included will allow you to customise the fit to your foot...give us a ring or an email, if you want some one-on-one advice how to do this.
All the linings are leather, as well as the uppers, and footbeds. The sole is PU, keeping them light weight, meaning your feet won't get tired!
