The Sidi Kaos are provided with the Soft Instep Closure System. This is an anatomically shaped, comfortable strap on top of the foot in a soft and thermal material. The new Tecno-3 dial mechanism allows you to close the shoe in its entire length, and it adjusts to the shape of your foot. The Millennium 4 Carbon sole is made of nylon enhanced carbon fibre. The carbonfibre offers more stability to the sole, is more durable, and resistant to changes in stiffness of the sole because of long-term use and temperature changes.

Extensive explanation size in cm
The size denoted in cm tells you how long the shoe is. This size was taken on the inside of the shoe measuring from the heel to the toes. In order to determine what size you’ll need, you can measure your own foot. Do this by placing a piece of paper on the floor tucked against the wall. Stand on the paper with your heel against the wall. Draw a line at your big toe. Measure the distance between that and the wall, and add approximately 5 mm. The number of centimeters is the size in centimeters found on our website. Which specific EU/UK size you need can differ between brands. This is because each brand uses their own boot tree, causing the shoe to be bigger or smaller than the size would suggest. This is why we’ve added the size in centimeters for all of our shoes. We’ve also categorised our shoes in three different groups: narrow, medium, and wide. In order to determine the width of your foot, you can use this table. Read all about it on our blog!

Heerlijke schoenen met mooi design

Schoenen zien er goed uit en zitten heerlijk. Alleen een nadeel is dat in het begin de flap aan de bovenkant was stroef is en er een kartelrandje aan zit. In het begin deed dit pijn aan mijn voet, maar na een tijdje begon deze soepeler te worden en was dit geen probleem meer.

Geweldige schoenen in comfort en gebruiksgemak.

Zitten erg prettig en zijn gemakkelijk en nauwkeurig in te stellen. Inmiddels weet ik precies hoe ik ze elke keer hetzelfde kan afstellen. Ook het weer uitdoen gaat erg gemakkelijk. Enig min puntje is het minder ademde comfort.

  • Comfort
  • Afstellen erg gemakkelijk en snel
  • Robuust
  • Minder goed ademend

Prachtige schoenen!

Zijn ze duur? Eigenlijk wel! Zijn ze mooi? Jazeker! Prachtige witte schoenen! Zitten ze lekker? Voor mijn lange (maat 47), smalle voeten, zeker! Als gegoten! Het feit dat ze geen klittenband hebben is voor mij een extra pluspunt (Denk aan de overschoenen voor de frissere dagen). Zeer tevreden klant!

  • Kleursamenstelling
  • Uiterlijk
  • Geen klittenband
  • Pasvorm (voor smalle voeten)
  • Kleinere maat

Detailed product description

Millennium 4 Carbon Sole
Made of nylon enhanced with carbon fibre. Carbon fibre offers the sole more stability, is more durable, and better resistant against changes in the stiffness of the sole caused by long-term use and temperature changes.

Soft instep 2 system
This is an anatomically shaped, comfortable strap on top of the foot in a soft and thermal material. The strap distributes pressure equally over the foot arch and can be adjusted on both sides to achieve a perfect centered position. It is replaceable.

Tecno-3 system
The new Tecno-3 dial mechanism allows you to close the shoe in its entire length, and it adjusts to the shape of your foot. The reliable and replaceable closing is improved with a new thread which allows the system to be adjusted quicker and easier.

Caliper buckle
Closing system that allows the strap to be adjusted to the millimeter even during riding, by pulling the middle buckle. To open it, pull the buckles on the sides. With the button on top of the buckle you can open the strap.

Sidi heel
The enhanced heel keeps the feet in optimal position and prevents the shoe from losing its shape because of extreme performance or long-term use.
