Very lightweight and cost-efficient, the Klogs "Boca" clog is made of weather-proof polyurethane right here in the U.S.A. As with the leather "Naples" model, Boca has the "WOW" factor created by deep insoles and thick outsoles made of a special polyurethane that's super-comfortable. The anti-microbial footbed is removable so you can insert your own orthotics. The PU sole is both slip- and oil-resistant polyurethane. Limited Unisex sizing for women's whole sizes 6 to 14 in an extra-wide width. (Men: order 1½ to 2 sizes larger on women's scale for proper men's fit.)
