We are really sorry the WVSport Active Sandals are only available up to a EU39 to EU42 in women's sizing and not in larger sizes.
We would love to provide these in a bigger size range (like we do for a lot of our styles), but sadly it is not possible for us to do so right now.
We are sometimes limited to the sizes we can make a model in due to the components available to us.
We are not a large company and do not manufacture all of the components ourselves, so are dependent on what our suppliers offer. In this case, Vibram only make this outsole down to an EU39.
