The O'Neill Mutant shoes provide excellent protection for the feet while staying near the water. The neoprene material with variable thickness 6/5/4 mm ensures warmth and works best in water temperatures of 0° - 8°. The ultra-thin rubber sole with texture gives an excellent ground feel underfoot, preventing slipping on wet surfaces. The shoes are useful for walking on hot sand, and on rocky or dirty beaches they provide protection against injuries and cuts. They work best as a complement to swimwear for water sports enthusiasts. Additionally, glued and blind seams block water from entering inside, while also providing protection against wind. Harsh weather conditions are therefore not an obstacle to practicing water sports.
