Unbequemer geht es nicht

Ich habe mir die Schlafsocken gekauft, da ich mit den klassischen Heat Holders Strümpfen immer sehr zufrieden war. Leider waren die Strümpfe ein absoluter Fehlkauf und überwintern nach dem ersten Tragen im Schrank. Grund: Der Fersen und Zehenbereich wurde mit einem sehr unangenehmen, rauhen und hartem Material verstärkt. Warum dies gemacht wurde ist mir völlig unverständlich, schließlich sind Schlafsocken keinerlei Belastung ausgesetzt. Auf jeden Fall drücken die verstärkten Stellen derart unangenehm auf die Haut, das die Strümfe völlig unbrauchbar sind. Wer ein gutes Paar Schlafsocken benötigt setzt besser auf die klassischen Heath Holders, denn diese sind tatelos und bequem verarbeitet.
