Brown leather ankle boots. The Naturalizer Onset ankle boots have a rounded toe, a side zip closure and a smooth leather finish. The timeless ankle boots are crafted with a 6.5cm block heel. Naturalizer shoes have a supportive, shock absorbing insole at the strike contact under the ball of the foot, and the full length of the lining, and have a perforated insole board that uses a flexible soling material to relieve pressure for a more natural ‘toe-off’. The shoe’s lining allows airflow around the foot and enables moisture to dissipate, keeping the feet cooler and drier. Featuring a uniquely designed heel and toe shape to promote stability and a secure fit, the shoes have an outsole and heel that are thin, yet slip resistant, and are durable without any extra weight.
