Sizing & Fitting

Kangoo Jumps are unisex. They are very comfortable and the sizes quite flexible, because the padding of the liner (inner shoe) adapts to the shape of your foot (even to a wide foot).

Kangoo Jumps are marked with Men's sizes in the center back of the liner. They are only available in full sizes. If you normally wear a shoe size 7 ½ for instance, order the size above, that is 8. As a rule, when in doubt, rather order a larger size, as you will still feel comfortable if your Kangoo Jumps size is up to 1 size larger than your usual shoe size.

In the worst case, should the ordered size not fit you, do not worry: we offer an excellent customer service and will fix the problem to your satisfaction.
