VeloKicks sizing is inline with many major brands. As a comparative tool, sizing is on par with Specialized, Bont, etc. A 44 in S-Works will fit the same as a 44 VeloKicks. If in doubt, go with what Euro sizing you presently run in your shoes or contact us via email and we will be more than happy to help work out your proper size.
Both models of VeloKicks have been designed around a upper with generous volume, so half sizes are not offered. Our range is from 38 to 47, however if you're a size outside of this range please email us at firstname.lastname@example.org if enough demand for any particular size exists we will be able to consider the costs of additional moulds.
