These are ReefTourer marine shoes. They have been used only once. Size: 21cm These are adult marine shoes, but due to the smaller size, they may also be suitable for children. These are aqua shoes that can be used for the sea, river play, pools, snorkeling, etc. The non-slip sole allows for safe use. There are some minor scuffs from use and sand that could not be completely removed from the sole grooves, but the sole wear is minimal and the overall condition is good. Please check the photos before purchasing. There is a vanilla-like scent from the time of purchase, but it did not bother me as it is for use near water. Please refrain from purchasing if you are sensitive to smells. A storage bag is also included.
