Unisex slides with mask design by Rei. Sizes are listed first by US MEN'S, then followed by EU sizing after the forward slash ("/"). Please consult size chart - it's best to measure in mm and select your size based on that measurement. 

Ladies: size down 1.5 to 2 sizes for women's sizing. For example, if you wear a size US 6 in women's shoes, a men's US 4 should work for you.
