Yes! We have two basic types of product at OluKai, Mauka (towards the land) and Makai (towards the sea). Our Makai products are made to be water friendly and made from all synthetic material, no animal products. Our Mauka products are generally Closed Toe and predominately made with leather; however we do have Mauka closed toe styles that use canvas or twill that are 100% synthetic. View material details on the product details tab under each product. Vegan styles are noted in the product description on our site, but a place to start is our ‘Ohana sandals (synthetic) or our Menʻs Nohea Moku or Womenʻs Haleʻiwa if you want a closed toe style, both are 100% Vegan. Note that “synthetic leather” is 100% synthetic.
