Fizik Tempo R4 Overcurve Iridescent Road Cycling Shoes

The Fizik R4 Overcurve Iridescent is a road bike shoe for men which is both versatile and suitable for a wide range of cyclists. This Iridescent model looks great and flashy. The Overcurve shoe construction has a staggered collar that wraps around the ankle, tracing the alignment of the two bone protrusions: the lateral and medial ankle nodes. This results in an asymmetrical construction which ergonomically conforms to the foot’s anatomy. The BOA® IP1-B locking system allows the fit to be adjusted quickly and easily by a simple turn of the knob. This locking system can also be used easily and responsibly while cycling.

Sole and material
This road bike shoe features the new R4 outsole, which is characterized by a medium stiffness. This outsole is reinforced with carbon, creating an ideal balance between comfort and pedalling efficiency. However, the power transmission of the R4 outsole is not as good as that of a full carbon outsole. The upper is made of a mesh material laminated with PU plastic. This improves ventilation, resulting in a comfortable foot temperature.

So, are you looking for an eye-catching road bike shoe with a perfect balance between comfort and performance? Then the Fizik R4 Overcurve Iridescent is the ideal choice for you.

Detailed explanation of sizing in mm
In order to help you, as best we can, to choose the right size shoe we have measured all the shoes ourselves. All that's left for you to do is measure your own foot length, and we'll tell you which shoe size per brand suits you best. Does your foot length in mm not appear on the relevant product's page? Then that particular shoe is not available in a size that suits your foot length.

You can easily measure your foot length using an A4 sheet of paper, placed on the floor against a wall. Stand with one foot on the piece of paper, with your heel against the wall. Draw a line above your big toe (or above the index toe if that is longer). Now mark your other foot on the paper in the same way. Measure both - the measurement of your longest foot is your foot length in mm's! Please note: some manufacturers have their own measuring system, and as a result what appears on the shoebox can deviate from what we have measured.

What shoe size you need can differ per brand. This is because certain brands wear larger or smaller. To help you get the perfect fit, we've also classified the shoes as narrow, average, or wide fit. Read all about it in our blog!
