Black slip-on shoes Size: 6 ½. My feet are pretty much perfect for size 36 (see measurements below), so I believe they are a 36. Leather, lined with fabric. Heel height: 4cms I've had the heel plates and the sole linings replaced, so the shoes are in very good condition – no marks or scratches, although the lining looks a bit worn. Good shoes for summer or winter, bare or stockinged feet. To maybe help – these are my foot measurements: Foot length: both 23.5cms Across instep (floor to floor): both 14.5cms
