The Columbia Men's Megavent Water Shoes are designed to perform at a high level on land, in a boat, or right in the water. The uppers are made of ventilated mesh for breathability, which is supported by a polyurethane cage for support. Techlite cushioning midsoles use a lower durometer EVA foam, meaning they'll offer better support for long periods of time. Drainable midsole ports enhance airflow to keep you cool, as well as helping to shed water to dry out faster once you hit land. Omni Grip soles use razor siping for excellent traction in water or out.
