The second strap that?s closest to your ankle is very large and roomy. Although this is an exceptional set or it should be because it is Astro, and it wasn?t cheap at all it came broken. We do a lot of hiking and beach trips come spring and summer and a lot of places have water. Excellent value for the price!

I have not owned this long, so I can only give limited feedback on durability.
