Our secret
We could spend hours telling you how we arrived at this design, but a picture is worth a thousand words. This is the UpBikers sole:

Colour map
-
Red zone: a design that lets you change gear or brake without adding height or losing feel.
-
Blue zone: this is where we gain the most height, almost 4 cm.
-
Green zone: the area in contact with the ground, designed for maximum grip and the largest possible surface without getting in the way of changing gear or braking.
-
Yellow zone: an area that gradually reduces the height according to the angle of your foot, so you can walk short distances without having to take your UpBikers off.
