Zapatillas Northwave Sonic Tech SRS

Taking it up a notch does not just involve shifting up a gear; it also involves upgrading the rest of your gear. The Northwave Sonic Tech SRS is for the cyclist who wants more than just a basic shoe, as this will help take your riding experience to a new level. The Carbon Light-sole is extremely rigid, whilst offering superb ventilation through 5 dedicated slots. The SRS micrometric buckle gives you supreme adjustability and tightness compared to a regular velcro strap.

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.
