These are supposed to work for &#34;River and Water&#34;<br />Shoes. They are very large for the marked sizes. The Velcro strap closure ripped right off of the shoe the 2nd time I wore them. I have very small feet,'so the strap didn't break bc of too much pressure. It broke bc the Velcro is just glued to the outside of the shoe with low quality glue. the shoes also have no traction so they're useless for water or river shoes
