Beach swimming shoes, non-slip, flat shoes, suitable for swimming, surfing, boating, and fishing - Creek shoes, suitable for beach and creek activities, and outdoor activities. I bought these for my husband, but he went into the sea with his sandals on and didn't use them. I'm selling them to someone who needs them. Wakeboard boots made of gray neoprene material, size 48/49, 28 cm, with a durable rubber sole.
