Green Keiki (child size) Mermaid MonofinDid you know? Keiki means "child" in Hawaiian. It's pronounced kee kee. :) The Keiki monofins are for use with our M, L, and XL mermaid tail sizes. Our patented mermaid monofin (swim flipper) is the best monofin available (US Patents 9561401 and 9925416). Not only does it help you swim like a real mermaid, it keeps feet from sliding around, is so comfortable to wear, and won't break. Unlike other monofins, our swim fins do not require any babying.
