The Men's Grundens SeaKnit Boat Shoe is a water-friendly shoe for the boat deck. Easy on and totally comfy, this sneaker is lightweight and breathable for a full day under the sun. The upper is constructed of a 100% nylon engineered knit that is ready to wear with or without socks. Underfoot, an EVA midsole offers cushion and support, while the natural gum rubber outsole is non-marking and razor-siped for traction on wet surfaces.
