The Mary Jane Clog Sandal has an open toe and ventilation on the sides. The Troentorp clogs all come with our orthopedically constructed foot beds that are designed to promote even weight distribution. The foot beds also have raised heels and anatomical support for the scaphoid and metatarsal arches. All these features together with the Troentorp clogs' carved toe wells help to reduce lower back strain and leg and foot discomfort. In order to give the clogs their characteristic comfort and look, the cowhide leather uppers are wet-lasted before being nailed to the moisture-absorbing alder foot bed. The clogs have a sole made up of naturally varnished alder wood and 1" heat-bonded polyurethane with non-skid tread to give maximum stability and comfort (which makes the Troentorps into great nurse clogs and chef clogs and ideal for professionals that work on their feet all day long).
