Whether you're just starting out or are a seasoned cycle fanatic. The Bontrager Sonic WSD offers more than value for money. By the Boa L5-turn knob in combination with the inForm Race last this shoe will fit almost any foot.

The Bontrager's Bronze Series composite sole has a stiffness index of 8. This means that this shoe gets a good score in this price category. Bontrager has achieved this by giving the sole a unique double construction, the Power Truss principle. This makes the outsole much stiffer, without adding any extra weight. The shoe is suitable for three-bolt race cleats and two-bolt MTB cleats. The MTB cleat is not sunken in the sole.

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!
