The Donatello clogs come with multi adjustable upper leather straps to accommodate feet of varying heights and broader insteps. Our orthopedically constructed foot bed is constructed to give a more even weight distribution across the foot. The raised heel and anatomical support for the scaphoid and metatarsal arches together with the clogs' carved toe well 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).
