Amphibious Marine Shoes 23.5 cm Although the product category is listed as blue, the color is closer to navy. My son has a high instep, but he was able to wear them without any problems because they can be adjusted with Velcro. I only used them for less than two weeks in Hawaii last year. I washed them thoroughly, but some sand from that time is still attached. I think they are in good condition.
