Product Care

Our sandals are made to last fighting fast fashion in every step involved. But, we need your help in taking good care of your nu solemates. The footbed can be cleaned with bicarbonate of soda and a little dash of natural soap. In case your Nuos get wet, it is best to dry them immediately to avoid the metal buckles from rusting.
