The Mares Bungee Fin Straps created as a smart alternative to the steel spring straps, this unique fin strap relegates adjusting a fin strap to a thing of the past. Bungees exceed steel springs in all aspects: Higher elastic properties, unaffected by sun, salt and chemical agents, lower weight and lower cost, and Mares has 40 years of experience using bungees as a key element in spear guns. With the new Mares Bungee Strap donning and doffing a fin is a breeze and the comfort during the dive is guaranteed by the new ergonomic heel cover. The heel cover comes equipped with a large hand loop allowing easy pull-to-stretch the bungee strap effortlessly over the heel of your foot. Sold in pairs the Bungee Fin Strap is available in multiple sizes and is designed to fit all mares open heel fins.
