Better than average arch support. Die App umfasst neben dem Reiter (Untermenü) ?Profil? noch drei weitere. Fits better than standard as thicker cushions, can use old cushion if prefer as sound blocking is in the plastic inserts. My only hands-on reference is the KX-TCA60 and I can say that I like it a lot better than this KX-TCA430 in three dimensions: 1) clarity; 2) volume; and 3) comfort. I already threw the box out so I cant even return it. These shoes fit me like a dream and they have very supportive insoles as well.
