Would you please explain the sizing for this product? What are shoe size equivalent for Adult 1-6? Thanks. Jacqueline
Hello Jacqueline, these fins are for kids or small adults. The size is for shoe size. Those size in adult are men sizes so if you are getting this for a women you would round up one size. So if you wear a mens size 5-6 in a tennis shoe you would order the biggest size. Gender does not apply when it comes to the kids size.
