Used a few times, washed and then stored. Sand hasn't been completely removed. The size isn't indicated, so I'm not sure, but they fit snugly, with no extra space, on someone who wears 23cm shoes. The insoles came out, and I was using replacements, but I lost the right insole and am not using one ( ; ; ) They've been sitting for a while since I bought them, so I think there's some aging. - Brand: SOUTHERNPORT - Color: Black/Red - Design: Mesh material - Purpose: Marine shoes
