More incognito than the other colors, Bump’Air Black is your secret style weapon. It likes to get dressed up after dark, and it loves Depeche Mode, punk rock, and long walks on the sidewalks.


Unisex sizing & fit 

Our sneaker-shoe hybrids are unisex.We offer Euro unisex sizes from 35 to 45. We don’t do half sizes. See our size chart above.

For your comfort, we provide an extra pair of insoles with each box. Swap these in for a more snug fit.

How does the Bump’Air fit?

We have found  we tend to run a half (Euro) size bigger. If you are a half (Euro) size, most customers size down (example: if you are 38.5, we recommend you take a 38). However, you have a wider foot and you are a half size, we would suggest sizing up (example: you are 43.5, and we’d recommend you take a 44).

If you are a full size, we recommend you stick with your size. The extra pair of insoles in your package can be swapped in for a more snug fit.
