A versatile performance road cycling shoe, quick and easy to wear. With asymmetric Overcurve upper, moderately rigid R4 sole and single Boa closure, it is designed to fit a wide range of cyclists. Tempo Overcurve R4 is a versatile performance, quick and easy to wear. It is designed to suit a wide range of cyclists and many types of driving. This shoe has been created to offer an essential and timeless look: the classic considerations of a street shoe have been redefined with a distinct fizik identity and a sleek and snug construction. Iridescent options add a new twist to that style. The construction of the Overcurve shoe has a staggered collar that wraps the ankle, tracing the natural misalignment of the two bone protrusions of the ankle: the lateral and medial malleolos. The result is an asymmetrical shape, with the throat of the shoe curving on the foot from its outer to the inner part. The closure is fast and secure, with a single micro-adjustable Boa IP1-B dial. The new moderately rigid R4 sole - with 15% infused carbon fiber - creates a balance between comfort and pedal efficiency to make it a true all-rounder. It also provides efficient ventilation and internal ducting for temperature management and has cleat positioning suitable for aggressive aerodynamic positions.
